What could this dream mean?

Ok guys I don't know what is going on with me. Please if you don't believe in dreams then don't answer... I am dreaming again and I woke up with this image of ants coming out of a trash can. The dream was that I am in a store like Home depot or something, I am ignoring this man, I am trying to get away from him which i do by going outside. He follows me, where I see this dumpster and it has alot of trash in it and at the bottom there are ants all over. One bites me on the foot. What could this mean?
