The first part comes from [[Psyche (psychology)|psyche]], which means [[soul]] in [[Ancient Greece|Ancient Greek]]. The second part is the ending '-osis', which means ''illness or unnatural condition''. So psychosis means ''unnatural condition of the soul''. People with psychosis may have [[hallucination]]s. They can [[experience]] things that are not really there. They may also have [[delusion]]s, which are fixed [[Belief|beliefs]] and ideas that are usually false. Sometimes their [[personality]] changes, and they [[thought disorder|cannot think straight]]. Some of these thoughts may be [[paranoia|paranoid]]. Not every psychotic person has all of these problems. Psychotic people often act in strange ways. It is difficult for them to live a normal life as part of [[society]]. They often have trouble with making [[Friend|friends]], as most people do not understand them. Psychosis can affect people to different levels. Some people can continue with mostly normal lives, while other people will need a lot of medical help. There are many things that can make someone seem psychotic. These include [[poison]]s, [[drug]]s, diseases of the [[nerve|nervous system]], and other [[illness]]es. <ref name=Tsuang_et_al_2000>{{cite journal |authorlink= |date=July 2000 |title=Toward Reformulating the Diagnosis of Schizophrenia |url=https://archive.org/details/sim_american-journal-of-psychiatry_2000-07_157_7/page/1041 |journal=American Journal of Psychiatry |volume=157|issue=7 |pages=1041–1050 |doi= 10.1176/appi.ajp.157.7.1041 | pmid = 10873908 |last1=Tsuang |first1=Ming T. |last2=Stone |first2=William S. |last3=Faraone |first3=Stephen V. }}</ref><ref name=DELAGE_1995>{{cite journal |last=DeLage
