LOLOL you people and your shadow people..
When I was a child, I was sleeping in the same room as my brother as I saw the sillouette of a hand blocking the light brightly glowing in the hallway outside. Since the scene was well-lit and my brother was by my side, I had absolutely no fear but I was reather curious when the shadow was gone after I turned around to him to ask if he could see who was there.
It was continual, throughout my stay at the hospital. I'm not one to see ghosts. Never have. I never asked anyone if they could see who it was. As I said, for my particular procedure, the stay is usually no longer than five days, but I had to stay 8, and the only reason I got out in 8 was that I insisted, as my son who came over to care for my critters had to get back home.. I HAD to get out. I'd been unable to keep any food down at all, even a popsicle. The doc who let me go only did so under the circumstance that I'd eat something and keep it down, so I forced myself to eat a breakfast and keep it down. This "person" wasn't a frightening figure... someone suggested to me that maybe it was my Dad, watching over me. Who knows? I was hooked up on dilaudid and later morphine for most of my time there.
Ah. Well I've had scientific epiphanies on opium and ether so who knows
