It is only to point out that the visual hallucinations significantly more likely to be found in acute psihozah and usually nestoiki; Hearing, on the other hand, often point to the persistent chronic illness (such as schizophrenia). The taste, and especially olfactory hallucinations in schizophrenia usually indicates zlokacestvennom, rezistentne to therapy option psychosis. Has some special options hallucinations for the emergence of which requires certain conditions, such as sonne of the patient. Reed encountered in zasapanii are called gipnagogicakimi under-raising gipnopompicakimi.
