Many studies have been conducted to understand the main causes of the hallucinations, and considerable evidence has been accumulated indicating that long periods of isolation aren't directly related to the level of experienced hallucinations.Marvin Zuckerman & Nathan Cohen (1964). Sources of Reports of Visual Auditory Sensations in perceptual-isolation experiments. |

Schizophrenics appear to tend to experience fewer hallucinations while in REST as compared to non-psychotic individuals. A possible explanation for this could be that non-psychotic individuals are normally exposed to a greater degree of sensory stimulation in everyday life, and in REST, the brain attempts to re-create a similar level of stimulation, producing the hallucinatory events.From drugs to deprivation: a Bayesian framework for understanding models of psychosis |

According to a 2009 study published in the ''[[Journal of Nervous and Mental Disease]],'' the hallucinations are caused by the brain misidentifying the source of what it is currently experiencing, a phenomenon called [[faulty source monitoring]].{{Cite journal |last1=Mason |first1=O |last2=Brady |first2=F |year=2009 |title=The psychotomimetic effects of short-term sensory deprivation |journal=Journal of Nervous and Mental Disease |volume=197 |issue=10 |pages=783–785 |doi=10.1097/NMD.0b013e3181b9760b |pmid=19829208 |s2cid=23079468}} |

A study conducted on individuals who underwent REST while under the effects of Phencyclidine (PCP) showed a lower incidence of hallucination in comparison to participants who did not take PCP. The effects of PCP also appeared to be reduced while undergoing REST. The effects PCP has on reducing occurrences of hallucinatory events provide a potential insight into the mechanisms behind these events. |
