Deja Vu with bad endings?

This is really creepy. Like a lot of people I know, I have dreams and they not to far into the future. But here's the twist:my dreams always have horrible endings. The horrible endings never happen in realy life but the topic does. Example: dream-my friend, her little cousin, and I were bouncing on a trampoline. I didn't notice her little CPUs was getting off and I was still jumping and she ended up getting really hurt. Real life-The same thing happened except I stopped jumping when she was getting off. Oh, and I've never seen the little cousin before it really happened. Does this mean anything?
