I used to have recurring dreams in my 20s of being chased and unable to get away or of being in the house alone and someone breaking in. Dreams are generally understood as your brain attempting to resolve an emotional situation which your conscious mind cannot deal with.
Sometimes aspects in dreams are said to represent parts of your life as a metaphor. For example, a house might be a way of representing the self so those dreams of mine were, I now think, anxiety dreams about safety and security.
One of the best explanations I've read about dreams was in a book called Human Givens by Ivan Tyrrell and Joe Griffin. Its easy to find in libraries and on Amazon. In case you weren't aware, there are many theories on the meaning of dreams from the simplistic to the academic.
If you're worried about your dream, no qualified counsellor would be surprised by someone wanting the opportunity to talk about it.
