My dream last night concerns me.... :-/

Last night I had a dream that I got run over by a train and that I was crossing the tracks and boom that stupid clock,which sounded like a train went off and I woke up before I got hit with the train. Does this dream mean that I have a death wish or is sustainal or whatever? Probably not. Just means that I need to buy a book on whatever it is to make me not feel that way or dream anything like that ever again. *sigh*
