Just want to tell you what happened to me in 1999.
It was quick but wicked nonetheless...
I was propped up with my back against the headboard of my bed. I was watching a movie waiting for dinner. My wife was sitting at the computer to the left of the TV, her back to me. My 12 year old son walked in and stood directly in front of the TV (blocking my view) and proceeded to ask his mom a question. She turned around for a moment and answered his question, so he left the room. At the moment he left the room (turned right and out of sight), he walked back in. I sat there watching the entire identical thing happen again. Absolutely word for word, motion for motion. I do remember (purposely) my state of mind at the time. It was after a long day of work. I was very relaxed and nothing on my mind. Just chillin and watching an old black and white Western. And BAM! Crazy time slip.
I knew what had just happened but I couldn't even tell my wife at that moment. She would have thought I was crazy.
Anyway, it never happened to me again as far as I know. Just thought I'd share.
