Psychosis is a serious mental condition where someone loses touch with reality in ways that make it hard for them to know what's real and what isn't. A person experiencing psychosis might see or hear things that aren't actually there (called hallucinations), or firmly believe things that aren't true no matter what evidence they see (called delusions). For example, they might hear voices talking to them when no one is around, or believe that strangers on TV are sending them secret messages.

Psychosis is a medical condition, not something a person chooses or controls. It can happen for different reasons: sometimes as part of illnesses like schizophrenia, sometimes from extremely high fevers, severe sleep deprivation, or certain medications. Doctors can often help people with psychosis through medication and therapy, helping them reconnect with reality.

When someone is experiencing psychosis, they may be described as psychotic. This is completely different from the casual misuse you might hear in movies where someone calls another person “psycho” to mean angry or violent. Real psychosis is a treatable medical condition, and most people experiencing it are not dangerous. They need understanding and proper medical care, just like someone with any other serious health problem.
