Ok so here's the thing. I've been having the same dream continuously now for about a week and it's really starting to freak me out. Is it normal to have the same dream five nights in a row?

Ok here's the dream:

It starts with me surrounded by trees, but not the trees I'm used to here in Texas. They are much more tropical looking. Like rain forest trees. Anyway, I have no idea where I am and I begin to start looking around for anyone. I always take the same route too, it's never different.

So anyways, as I'm looking for anyone or something at all I my heart starts pounding really bad and it builds and builds until I can hear it in my ears. The fear of what ever is happening to me rises and then I wake up frightened and sweating.

So my question is: Is this normal? It's the same dream every time, and I'm getting really worried. It's kind of caused me to have insomnia because I don't want to go to sleep and have the dream again.
