Psychosis refers to an abnormal condition of the mind described as involving a loss of contact with reality. People with psychosis are described as psychotic. People experiencing psychosis may exhibit some personality changes and thought disorder.
Psychosis in general is considered to be an illness accompanied by delusions and/or hallucinations. Usually these hallucinations occur outside of the userâs understanding and scope of cognition. Hallucinations are primarily visual, and their effects can be elevated with the use of certain psychedelic drugs. Delusions, on the other hand, are shifts in the userâs reality in such that he or she believes something outside of what is really going on.
