I have had that happen before.Once while sitting in a movie i was talking to a friend through it and i pointed out everything that was going to happen without even seeing the movie.Mind you we went to the first showing of that movie and i have never seen it before.And while i was watching it, it felt like i already seen that movie a hundred times before.
Also when i was little i had a dream that my dog's head fell off for like no reason.No one choped it off or anything.Then the very next morning my grandfather came into my room and told me m dog died.
My grandmother also had an experience with this kind of stuff.She had a dream that her first husband who she was with at the time died in a car crash. And about a week later he did.
