I've had dreams about things that happened prior to them happening too many times for me to discredit this. For example: Early on the morning of 9/11/01 I had a dream that I was in some kind of large, room-sized elevator (probably some kind of service elevator) in a very tall building. Suddenly the elevator started to go into free fall and I was sort of floating above the floor of the elevator. When it hit the ground I woke up with a start - I remember thinking that it seemed unusually vivid. Went back to sleep and a few hours later the events of 9/11 were all over the news. It was a weird feeling. I've had dreams about earthquakes that happened hours later (even saw a map of the location in the dream), dreams about married friends getting a divorce that soon did (2 different couples), even a very quick dream about my mom dying... the night before she did (she had been ill, but she wasn't considered ill enough to be hospitalized, it was completely unexpected).
I don't know what to make of these dreams.
