Oneirophrenia

Oneirophrenia (from the Greek words "ὄνειρος" (oneiros, "dream") and "φρενός" (phrenos, "mind")) is a hallucinatory, dream-like state caused by several conditions such as prolonged sleep deprivation, sensory deprivation, or drugs (such as ibogaine). It has some of the characteristics of simple schizophrenia, such as a confusional state and clouding of consciousness, but without presenting the dissociative symptoms which are typical of that disorder.
