Abstract

To test the hypothesis that the wavelength (color) of ambient lightning should modulate experiences of a sensed presence when the right hemisphere was stimulated by weak, burst-firing magnetic fields, volunteers were exposed for 30 min to this condition or to a sham field while they sat (eyes opened) in either dim red, green, or white light. Subjects exposed to the magnetic field reported significantly more visual sensations along the left side in red light and along the right side in green light. The significant interaction between ambient color and the field treatment was due to the marked increase in experiences of dizziness, sensed presence, "ego-alien" thoughts, and detachment from the body and "being somewhere else" for subjects exposed to the magnetic field while sitting in red light. The concurrence of entoptic images experienced within the upper left peripheral visual field and the sensed presence supported the hypothesis that both are associated with the intrusion of right hemispheric processes into left hemispheric awareness.
