minor hallucination
   The term minor hallucination is indebted to the Latin adjective minor, which means smaller, younger, the youngest. It is used to denote a * sensory deception that does not fulfil the criteria of a * hallucination proper, such as a *hallucinoid or illusory phenomenon. Some phenomena classified as minor hallucinations are *sensed presence, * passage hallucinations, and *cognitive illusions. Minor hallucinations can occur in healthy individuals, but they are also associated with a variety of psychiatric and neurological conditions, including narcolepsy, Parkinson's disease, and the use of illicit substances such as cannabis, Amanita muscaria, mescaline, and LSD.
