In my book with Dr. Marc Miocozzi, The Spiritual Anatomy of Emotion, I discuss the way a life-threatening emergency marshals the complete attention of body and mind – and how the energy involved may, in some cases, upend the normal convergence of space/time so that anomalous perceptions result. The dynamics frequently, though not inevitably, involve people (or animals) that have emotional ties to one another. When such bonds do not exist, the person (or animal) involved is likely to be highly sensitive, physically and/or emotionally.
This theory is elaborated upon in a soon-to-be-published book by Brandon Massullo, a therapist practicing in suburban Cleveland. According to Massullo, it’s plausible that “traumatic events trigger conscious and unconscious processes [that] seek to alleviate our distress or communicate it to others.” (Massullo, p. 67) A person who is dying or facing the threat of death may – especially if the circumstance is sudden or unexpected – experience “a myriad of…volatile emotions” ranging from fear to sadness to regret to anger. These feelings may emanate, like a distress signal, to certain others. (Massullo, p. 119)
The capacity, I suggest, is akin to a phenomenon known as prodromal dreaming, a term used by the late dream researcher Robert Van de Castle. He observed that "dreams can be sensitive indicators of biochemical or physiological changes." (Van de Castle, p. xix) Such dreams have been noted by observers going back to antiquity. The renowned second-century Greek physician Galen mentioned the case of a man who dreamed his leg had turned to stone and whose leg developed paralysis a few days later. (Van de Castle, p. 364) Van de Castle proceeds to offer several more modern examples (pp. 368-9):
It would seem that dreams can, at least in some people, function as a virtual x-ray. Given how entwined and continuous is the communication between our brain and body, it's not surprising that physiological information should come into awareness during sleep. This is, after all, when the brain is most likely to retrieve and assess subliminal information.
