Why do we dream about certain people?
In my opinion, the reason why we dream about certain people is because we think of them too much. For example, if you think so much about your boyfriend or girlfriend when going to sleep, it sticks in your leading to that.
I agree with rickyrich
Because they've touched u in your life somehow.
