Are "presences" preferentially felt along the left side of one's body?
The "feeling of a presence" is the distinct awareness of the physical presence of somebody in the near extracorporeal space. Although fairly frequently confined to one side of the body, systematic documentation of the lateralization of the phenomenon has not yet been attempted. A brief tabular summary of 11 cases of the unilateral feeling of a presence in association with focal brain pathology (seven left-hemisphere lesions, four right-hemisphere lesions) shows lateralization to the left in five, to the right in six cases. The data, together with the scattered reports of unilaterally felt presences in patients with nonfocal brain pathology and in healthy individuals, do not support claims that the left hemispace is the preferred location. Any models of hemispheric specialization in the sense of self which are derived from observations of felt presences remain speculative. Nevertheless, clinicians are encouraged to document carefully all the unilateral aspects of the feeling of a presence as well as of other reduplicative phenomena involving the self.
