Being chased but never caught/hurt...

Of the dreams that I can remember of this type, I'm always seem like i'm being chased or attempted to be hurt, but never are hurt completely. The first dream was myself in my car and these dogs were trying to attack me as I was driving down this street. They would knick at me or try to bite me but I could never be physically hurt really. Second dream was basically the same idea but with snakes this time, but I was walking around with my brother near a friends house. Third time this happened was last night and I was with my girlfriend, And there was this father figure , It was supposed to be hers , but it didnt look like him or even close. And he was verbally attacking us , but mostly directed towards her I think. And he was chasing us through this mase filled like house. We wind up in this living room and its filled with home entertainment equipment , and I always have my eye on the surround sound for some reason, saying to her should I take it? leave it? Funny thing is it feels like I dream about being in this living room alot of the time with this ordeal happening. Just wanted to know your thoughts about if this means anything. Thanx Jeff
