This state of mind is commonly associated with and occurs along side of a very similar psychological disorder known as depersonalization. While derealization is a perception of the unreality of the outside world, depersonalization is a subjective experience of unreality in one's sense of self. | This state of mind is commonly associated with and occurs along side of a very similar psychological disorder known as depersonalization.

In psychology, symptoms of chronic derealization | In psychology, chronic derealization that persists during sobriety for prolonged periods of time is identified as "derealization disorder" and is classified by the DSM-IV as a dissociative disorder. While degrees of derealization are common and can happen temporarily to anyone who is subject to an anxiety or stress provoking situation, chronic derealization is more common within individuals who have experienced a severe trauma or prolonged stress and anxiety. The symptoms of both chronic derealization and depersonalization are common within the general population, with a lifetime prevalence of up to 26-74% and 31–66% at the time of a traumatic event.<ref>The epidemiology of depersonalisation and derealisation. A systematic review | https://www.ncbi.nlm.nih.gov/pubmed/15022041</ref> It has been demonstrated that derealization may be caused by a dysfunction within the brains visual processing center (occipital lobe) or the temporal lobe, which is used for processing the meaning of sensory input, language comprehension, and emotion association.<ref>Separating depersonalisation and derealisation: the relevance of the “lesion method” (bmj.com) | http://jnnp.bmj.com/content/72/4/530</ref> | ||
Derealization is a particularly common accompanying effect during states of hallucinogen induced anxiety. It is most commonly induced under the influence of moderate dosages of dissociative compounds such as ketamine, MXE, DCK, and 3-MeO-PCP. However, it may also occur less commonly on other types of hallucinogens and during withdrawals from stimulants or depressants.</onlyinclude> | Derealization is a particularly common accompanying effect during states of hallucinogen induced anxiety.
