This study provides a short review of certain anomalous experiences such as glossolalia and out-of-body experiences, which are frequently experienced by a number of the healthy as well as the pathological population. Research also suggests that these experiences may be of a transformative and transcendent nature and linked to positive psychological well-being. Further, they may share similar phenomenological and semiological features. They all belong to the category of altered states of consciousness and are mostly treated by current psychiatry as pathological (...) problems, rather than spiritual or religious, as suggested by some studies.
