I have a question about fainting. I have noticed when I get my blood taken or getting a shot. When I faint I have these flashbacks of my life. It's like reliving memories I had forgotten so long ago. When I wake up I can't remember what I had dreamt about. I am wondering is this something normal when you faint? Many people have told me when they faint that everything just goes dark and then they come to. So I'm wondering if my subconscious mind might be unlocking these memories.
