What does it mean if I had a dream about getting robbed?

I had a few different dreams last night. The first was similar to a dream i had months ago. Both times a man was trying to break an entry to steal something and both times he was trying to get in from the sliding glass window on the side of my house. In the first one he got in but ran out when we saw each other in the second he didn't get in but threw rocks at the sliding window. In the dream I had last night me and my dad armed are self and a few of my friends came to my house because the man who tried to get in turned out to be a crazy person on the lose going from house to house. Later that night i had different dreams of other people that I kind of know robbing or stealing from random people i have never seen. There was lots of violence and demented things happening but i wasn't necessarily there i some how could just see everything. The things that were happening were similar to the movie "The Crazies" which i watched for the first time last Mon. Anybody know what these dreams mean?
