Many people have gone through unusual experiences that they believe are real. Hallucinations connected to religion or paranormal experiences seem to be quite common. Very often, these experiences cannot be called "psychosis" in a medical sense of the word. For this reason, some people have said that psychosis may simply be an extreme case of something that is experienced by most. People who have suffered from what could be called "psychosis" may simply have had experiences that were very strong or distressing.
