People with aphantasia see only a faint image or none. About 4 in 100 people are like this, and about 1 in 100 see nothing at all. A few people have images almost as vivid as real sight. https://vester.si/bodily-oddities/oddities/camptodactyly/ https://vester.si/bodily-oddities/oddities/camptodactyly/ Fri, 11 Sep 2026 12:02:40 GMT A finger that stays bent forward at its middle joint and cannot fully straighten, usually the little finger. Under 1% of people have it. Mild cases rarely cause trouble, but the bend can get worse while a child grows. https://vester.si/bodily-oddities/oddities/linburg-comstock-variation/ https://vester.si/bodily-oddities/oddities/linburg-comstock-variation/ Fri, 11 Sep 2026 12:02:40 GMT An extra tendon link in the forearm that ties the thumb to the index finger. When the thumb bends into the palm, the index fingertip bends with it. Roughly 1 in 5 people have it, but counts vary widely. https://vester.si/bodily-oddities/oddities/oculocardiac-reflex/ https://vester.si/bodily-oddities/oddities/oculocardiac-reflex/ Fri, 11 Sep 2026 12:02:40 GMT Pressure on the eyeball, or a pull on an eye muscle, makes the heart slow down. It matters most during eye surgery, especially in children. It is not a safe way to slow your own heart. https://vester.si/bodily-oddities/oddities/proctalgia-fugax/ https://vester.si/bodily-oddities/oddities/proctalgia-fugax/ Fri, 11 Sep 2026 12:02:40 GMT A sudden, cramping pain deep in the rectum that lasts seconds to minutes and then goes away completely. It has no known cause, and it is harmless. https://vester.si/bodily-oddities/oddities/asmr/ https://vester.si/bodily-oddities/oddities/asmr/ Tue, 01 Sep 2026 19:04:57 GMT A pleasant tingling that starts on the scalp and moves down the neck and spine, set off by whispering, tapping, soft sounds, or gentle personal attention. Not everyone gets it. A large online community is built around it. https://vester.si/bodily-oddities/oddities/benign-fasciculations/ https://vester.si/bodily-oddities/oddities/benign-fasciculations/ Tue, 01 Sep 2026 19:04:57 GMT Small visible twitches in the eyelid, calf, thumb, or arm that come and go with no weakness. About 70% of healthy people get them. They are not a sign of nerve disease. https://vester.si/bodily-oddities/oddities/bppv/ https://vester.si/bodily-oddities/oddities/bppv/ Tue, 01 Sep 2026 19:04:57 GMT A short, intense spinning feeling set off by turning over in bed or tipping your head back. Tiny crystals in the inner ear have drifted into the wrong place. It is the most common cause of vertigo and it is very treatable. https://vester.si/bodily-oddities/oddities/brain-freeze/ https://vester.si/bodily-oddities/oddities/brain-freeze/ Tue, 01 Sep 2026 19:04:57 GMT A short, sharp headache in the forehead a few seconds after cold food or drink touches the roof of the mouth. It passes in under a minute. https://vester.si/bodily-oddities/oddities/brain-zaps/ https://vester.si/bodily-oddities/oddities/brain-zaps/ Tue, 01 Sep 2026 19:04:57 GMT A brief feeling like a small electric shock inside the head, often set off by moving the eyes.

About half of people get it. It is the brain's safety system being misread, not a hidden wish. https://vester.si/bodily-oddities/oddities/deja-vu/ https://vester.si/bodily-oddities/oddities/deja-vu/ Tue, 01 Sep 2026 19:04:57 GMT A strong feeling that you have lived the present moment before, even though you know you have not. Almost everyone gets it. It peaks between the ages of 15 and 25. https://vester.si/bodily-oddities/oddities/derealization-depersonalization/ https://vester.si/bodily-oddities/oddities/derealization-depersonalization/ Tue, 01 Sep 2026 19:04:57 GMT The world suddenly seems flat, distant, or like a film (derealization), or you feel like you are watching yourself from outside (depersonalization). Most people have a brief episode at some point, usually under stress. https://vester.si/bodily-oddities/oddities/exploding-head-syndrome/ https://vester.si/bodily-oddities/oddities/exploding-head-syndrome/ Tue, 01 Sep 2026 19:04:57 GMT A loud bang, crash, or explosion heard inside the head while falling asleep or waking up. Nothing actually happens, there is no pain, and it is harmless. https://vester.si/bodily-oddities/oddities/floaters/ https://vester.si/bodily-oddities/oddities/floaters/ Tue, 01 Sep 2026 19:04:57 GMT Small grey threads, dots, or cobwebs that drift across your vision and dart away when you look at them.

They are ordinary oil glands in a place without hair. Most adults have them. https://vester.si/bodily-oddities/oddities/frisson/ https://vester.si/bodily-oddities/oddities/frisson/ Tue, 01 Sep 2026 19:04:57 GMT Goosebumps and a wave of chills down the back at a powerful moment in music, a film, or a speech. About half of people get it regularly. It comes from the brain's reward system reacting to an expectation being met or broken. https://vester.si/bodily-oddities/oddities/hypnagogic-hallucinations/ https://vester.si/bodily-oddities/oddities/hypnagogic-hallucinations/ Tue, 01 Sep 2026 19:04:57 GMT Vivid images, sounds, or touches that appear while you are falling asleep or waking up. A face, a voice saying your name, a hand on your shoulder. They are dream fragments arriving early or late, and they are normal. https://vester.si/bodily-oddities/oddities/hypnic-jerks/ https://vester.si/bodily-oddities/oddities/hypnic-jerks/ Tue, 01 Sep 2026 19:04:57 GMT A sudden jolt of the arms, legs, or whole body just as you fall asleep, often with a feeling of falling. Most people get them, and they are harmless. https://vester.si/bodily-oddities/oddities/migraine-aura/ https://vester.si/bodily-oddities/oddities/migraine-aura/ Tue, 01 Sep 2026 19:04:57 GMT A shimmering zigzag or C-shaped patch of light that grows across your vision over 5 to 60 minutes and then fades. It can come before a migraine headache or, in some people, with no headache at all. https://vester.si/bodily-oddities/oddities/pee-shivers/ https://vester.si/bodily-oddities/oddities/pee-shivers/ Tue, 01 Sep 2026 19:04:57 GMT A brief involuntary shudder during or just after urinating. Most men and many women get it. It is widely known and almost completely unstudied. https://vester.si/bodily-oddities/oddities/phantom-phone-vibrations/ https://vester.si/bodily-oddities/oddities/phantom-phone-vibrations/ Tue, 01 Sep 2026 19:04:57 GMT You feel your phone buzz in your pocket, check it, and nothing happened. Most phone users get this. It is a normal learning effect in the brain, not a fault. https://vester.si/bodily-oddities/oddities/phosphenes/ https://vester.si/bodily-oddities/oddities/phosphenes/ Tue, 01 Sep 2026 19:04:57 GMT The flashes, rings, and patterns of light you see when you rub or press your closed eyes, or after a knock on the head. The retina fires from pressure instead of light. https://vester.si/bodily-oddities/oddities/pins-and-needles/ https://vester.si/bodily-oddities/oddities/pins-and-needles/ Tue, 01 Sep 2026 19:04:57 GMT The prickling, buzzing feeling in a limb after you sit on it or lean on it. It happens when pressure comes off a nerve and the nerve fibres restart at different speeds. https://vester.si/bodily-oddities/oddities/pruney-fingers/ https://vester.si/bodily-oddities/oddities/pruney-fingers/ Tue, 01 Sep 2026 19:04:57 GMT Fingertips and toes wrinkle after 5 to 15 minutes in water. This is not the skin soaking up water. It is the nervous system shrinking the fingertip on purpose, and the wrinkles may improve grip when wet. https://vester.si/bodily-oddities/oddities/random-shivers/ https://vester.si/bodily-oddities/oddities/random-shivers/ Tue, 01 Sep 2026 19:04:57 GMT A single brief shudder that runs down the spine or through the whole body when you are not cold.

Nobody has counted them. https://vester.si/bodily-oddities/oddities/rubber-hand-illusion/ https://vester.si/bodily-oddities/oddities/rubber-hand-illusion/ Tue, 01 Sep 2026 19:04:57 GMT Stroke a rubber hand and a person's hidden real hand at the same time, and within a minute or two the brain adopts the rubber hand as its own. It shows that your sense of your body is built moment by moment from sight and touch. https://vester.si/bodily-oddities/oddities/seeing-stars-when-standing/ https://vester.si/bodily-oddities/oddities/seeing-stars-when-standing/ Tue, 01 Sep 2026 19:04:57 GMT You stand up fast, your vision goes grey or sparkly, and your head feels light for a few seconds. Blood has briefly pooled in your legs. It passes on its own. https://vester.si/bodily-oddities/oddities/sleep-paralysis/ https://vester.si/bodily-oddities/oddities/sleep-paralysis/ Tue, 01 Sep 2026 19:04:57 GMT You wake up, or start to fall asleep, and cannot move or speak for a few seconds to minutes. Sometimes a threatening presence seems to be in the room. It is the normal paralysis of dreaming sleep running a little late. https://vester.si/bodily-oddities/oddities/tinnitus/ https://vester.si/bodily-oddities/oddities/tinnitus/ Tue, 01 Sep 2026 19:04:57 GMT A ringing, hissing, buzzing, or roaring sound with no source outside your head. Between 15% and 20% of people have it. It is mostly the hearing system filling in for damaged or tired inner-ear cells. https://vester.si/bodily-oddities/oddities/tonsil-stones/ https://vester.si/bodily-oddities/oddities/tonsil-stones/ Tue, 01 Sep 2026 19:04:57 GMT Small white or yellow lumps that form in the folds of the tonsils and sometimes come out when you cough.

The visual part of the brain is over-active. https://vester.si/bodily-oddities/oddities/alice-in-wonderland-syndrome/ https://vester.si/bodily-oddities/oddities/alice-in-wonderland-syndrome/ Tue, 01 Sep 2026 19:03:08 GMT Objects, body parts, or the whole room suddenly look far too big, far too small, or far away. It mostly happens to children, often during a fever or infection, and it passes on its own. In adults it is usually linked to migraine. https://vester.si/bodily-oddities/oddities/ccr5-delta32/ https://vester.si/bodily-oddities/oddities/ccr5-delta32/ Tue, 01 Sep 2026 19:03:08 GMT About 1% of people of Northern European descent carry two copies of a broken gene that makes them almost immune to the most common form of HIV. A bone marrow transplant from one such donor produced the first cure of HIV. https://vester.si/bodily-oddities/oddities/chimerism/ https://vester.si/bodily-oddities/oddities/chimerism/ Tue, 01 Sep 2026 19:03:08 GMT A chimera is one person made of two sets of cells with different DNA. It happens when two embryos fuse in the first days of pregnancy. Most chimeras never find out. A few discovered it when a DNA test said they were not the mother of their own children. https://vester.si/bodily-oddities/oddities/congenital-insensitivity-to-pain/ https://vester.si/bodily-oddities/oddities/congenital-insensitivity-to-pain/ Tue, 01 Sep 2026 19:03:08 GMT A tiny number of people are born unable to feel pain. Single-gene changes switch off their pain nerves. It is not a superpower. Injuries go unnoticed, and most people with it are badly hurt in childhood. https://vester.si/bodily-oddities/oddities/eidetic-memory/ https://vester.si/bodily-oddities/oddities/eidetic-memory/ Tue, 01 Sep 2026 19:03:08 GMT Some children can keep a detailed picture of an image in view for a short time after it is taken away. The ability fades by the teenage years. A true photographic memory in adults has never been confirmed. https://vester.si/bodily-oddities/oddities/extraordinary-breath-holding/ https://vester.si/bodily-oddities/oddities/extraordinary-breath-holding/ Tue, 01 Sep 2026 19:03:08 GMT Untrained adults usually stop within a minute or two. Trained freedivers manage over 11 minutes, and over 29 minutes after breathing pure oxygen. One group of sea nomads has evolved larger spleens for diving. https://vester.si/bodily-oddities/oddities/geometric-nightmares/ https://vester.si/bodily-oddities/oddities/geometric-nightmares/ Tue, 01 Sep 2026 19:03:08 GMT A kind of dream, usually during fever in childhood, filled with huge or tiny shapes, infinite space, crushing pressure, and dread. The name comes from an online forum, not a medical text, but each piece of it is well known to neuroscience. https://vester.si/bodily-oddities/oddities/hsam/ https://vester.si/bodily-oddities/oddities/hsam/ Tue, 01 Sep 2026 19:03:08 GMT Fewer than a hundred people worldwide have been confirmed to recall what happened on almost any date of their adult lives, in detail and without effort. Their memory for other things, such as lists or numbers, is ordinary. https://vester.si/bodily-oddities/oddities/human-echolocation/ https://vester.si/bodily-oddities/oddities/human-echolocation/ Tue, 01 Sep 2026 19:03:08 GMT Some blind people find their way by making sharp tongue clicks and listening to the echoes. Brain scans show the echoes are processed in the visual cortex. Sighted people can learn a basic version in a few weeks. https://vester.si/bodily-oddities/oddities/meditation-body-dissolution/ https://vester.si/bodily-oddities/oddities/meditation-body-dissolution/ Tue, 01 Sep 2026 19:03:08 GMT During long, still meditation the brain loses track of the arms and the edges of the body. Hands can feel close to the shoulders and far away at the same time. Flotation tanks produce the same effect. It is harmless. https://vester.si/bodily-oddities/oddities/mirror-touch-synesthesia/ https://vester.si/bodily-oddities/oddities/mirror-touch-synesthesia/ Tue, 01 Sep 2026 19:03:08 GMT About 1 in 60 people feel a touch on their own body when they watch someone else being touched. The brain system that mirrors other people's actions appears to be turned up too high. https://vester.si/bodily-oddities/oddities/perfect-pitch/ https://vester.si/bodily-oddities/oddities/perfect-pitch/ Tue, 01 Sep 2026 19:03:08 GMT About 1 in 10,000 people can name or sing any musical note without hearing a reference note first. It runs in families and is far more common in people who started music lessons very young. https://vester.si/bodily-oddities/oddities/pinocchio-illusion/ https://vester.si/bodily-oddities/oddities/pinocchio-illusion/ Tue, 01 Sep 2026 19:03:08 GMT Vibrate the biceps tendon while a person touches their own nose with their eyes closed, and their nose feels as if it is growing. It shows how the brain works out where the body parts are. https://vester.si/bodily-oddities/oddities/short-sleeper-syndrome/ https://vester.si/bodily-oddities/oddities/short-sleeper-syndrome/ Tue, 01 Sep 2026 19:03:08 GMT A small number of people need only 4 to 6 hours of sleep a night, wake without an alarm, and feel fine. Several gene variants have been linked to it. Most people who sleep that little are simply sleep-deprived. https://vester.si/bodily-oddities/oddities/supertasters/ https://vester.si/bodily-oddities/oddities/supertasters/ Tue, 01 Sep 2026 19:03:08 GMT About a quarter of people taste bitter compounds far more strongly than everyone else.

Fewer than 1% of people are truly ambidextrous. Most people who say they are ambidextrous are mixed-handed: right hand for some jobs, left for others. https://vester.si/bodily-oddities/oddities/cloverleaf-tongue/ https://vester.si/bodily-oddities/oddities/cloverleaf-tongue/ Tue, 01 Sep 2026 19:02:32 GMT Folding the tongue into three lobes, like a clover leaf. Between 10% and 15% of people in Western samples can do it.
