Wow - crazy that. I had outlined a screenplay a few years ago in which an elderly man with cataracts undergoes a new surgical procedure. Upon wakening, he is surrounded by his family and friends - none of whom are the same people! They all claim to be his immediate family and closest friends, but despite all the houses and cars and geographies remaining the same, the people have utterly changed in physical looks and demeanor. It gets dark and scary from there, a little along the lines of Jacob's ladder.
Curiously, during the operation i had described an other-wordly journey he undertook which later becomes one of the folds in the mystery.
Maybe I'll dust it off and make it about CBS (wonder if the network is aware of the name of this phenomena!).
Thanks for the stimulating info and the link.

JBArk is a Mandelthought; a non-fiction character in a drama of his own design he calls "LIFE" who partakes in consciousness expanding activities and substances; he should in no way be confused with SWIM, who is an eminently data-mineable and prolific character who has somehow convinced himself the target he wears on his forehead is actually a shield.
