I don't really remember what context this happens in but in a lot of my dream's I am falling in one way or another. I remember one recently where it was simply a massive slide in the dark that got faster and faster and was approaching a light at the end of the tunnel then it ended. It was the kind where you falling so sharply you get that adrenalin feeling in your stomach.

Thing's like that seem to be a re-occurence in my dreams so is it a possibility that it is a dream sign?
