In case studies fantasy proneness has been shown to be higher among OBErs than those who have not had an OBE. The data has shown a link between the OBE experience in some cases to fantasy prone personality (FPP). In a case study involving 167 participants the findings revealed that those who claimed to have experienced the OBE were "more fantasy prone, higher in their belief in the paranormal and displayed greater somatoform dissociation." Research from studies has also suggested that OBEs are related to cognitive-perceptual schizotypy.
