It occurs to me that death is the ultimate "depersonalization", followed by general anesthesia. I was under anesthesia once for over 5 hours. I have no clue where that time went. No dreams, no pain, ....nothing. I suppose those 5 hours could have been extended to an eternity, given the seriousness of the operation. I probably would have been none the wiser. In any event, no individual has ever complained about his/her death.
