random, lol. i once was sittin around a campfire with some friends of mine, and we had the wood up in a teepee shape (pyramid) and i was just staring into space, looking at the fire, when i saw a log fall onto someones leg. now, this was only me seeing this (didnt actually happen). then 30 seconds later, the log fell, hit this chicks leg, and it looked like an EXACT replay of my "vision".
