These wild brain things can actually happen and that makes them even more wild. Do you think you know what they are?
The Belief That You’re Already Dead: Cotard’s Delusion
Some people with Cotard’s delusion genuinely believe they have died. They
may insist that their organs are missing, their body has stopped functioning, or that they no longer exist. In particularly extreme cases, someone may believe they are a walking corpse. The experience can be terrifying because the belief feels completely real to the person experiencing it.
Believing Someone Has Been Replaced: Capgras Delusion
Imagine looking directly at your mother, spouse, or friend and becoming convinced that they are an impostor. This can happen with Capgras delusion. A person recognizes the individual’s face but doesn’t experience the expected feeling of familiarity, causing the brain to construct an explanation: They look like the person I know, but they aren’t actually them.

Being Unable to Recognize Faces: Prosopagnosia
Some people have extraordinary difficulty recognizing faces, even the faces of people they know extremely well. This condition is known as prosopagnosia, or face blindness. Someone may recognize a person’s voice, clothing, hairstyle, or mannerisms while having no idea who they are from their face alone.
Hearing Music That Isn’t Playing
Musical hallucinations can cause people to hear songs, melodies, or voices when there is no external sound. Some people report hearing familiar songs repeatedly, while others experience elaborate orchestral music. It can be especially confusing when the imagined sound is incredibly realistic.

Feeling Like Part of Your Body Isn’t Yours
Certain neurological disorders can cause disturbances in body ownership. A person may feel that an arm or leg doesn’t belong to them, even though they can see it physically attached to their body. The brain normally creates our sense of having a unified body, but damage or disruption to particular brain networks can interfere with that experience.
The Feeling That You’ve Already Experienced the Present: Déjà Vu
Déjà vu is the strange sensation that you’re experiencing something you’ve experienced before, despite knowing logically that you haven’t. Scientists believe it may involve unusual interactions between memory and perception. The experience can be so convincing that people sometimes wonder whether they’ve somehow seen the future.

Sleep Paralysis
During sleep paralysis, a person can temporarily become unconscious while their body remains unable to move normally. Some people also experience vivid hallucinations, including shadowy figures, strange sounds, pressure on their chest, or the sensation that someone is standing nearby. Historically, experiences like these may have contributed to stories about demons, spirits, or supernatural visitors.
Remembering Something That Never Happened
Human memory isn’t a perfect recording. People can confidently remember events that never occurred. False memories can sometimes become extremely detailed, including locations, conversations, and emotions. Even more surprisingly, groups of people can occasionally develop similar mistaken memories.

Feeling Outside Your Own Body
Some people experience depersonalization or out-of-body sensations in which they feel detached from themselves or as though they’re observing their body from somewhere else. The experience can be intensely realistic even though the person’s physical body hasn’t actually moved.
The Brain as a Reality Generator
Perhaps the strangest lesson is that perception isn’t simply the brain recording the world. Your brain constantly interprets incomplete information, predicts what should happen, and constructs your conscious experience. When those systems malfunction, the result can be extraordinarily strange—sometimes making an impossible experience feel completely real.
