“I see myself lying in bed, from above, but I only see my legs.” The common factor in cases like these is unusual activity in brain regions that deal with vestibular input (the vestibular system deals with the sense of balance) and that are also involved in multisensory integration. It seems that when normal activity in these systems becomes disrupted, the brain can reach an unusual “best guess” about the location of its first-person perspective, even while other aspects of selfhood are left unaltered.
