dreams, nothing but silly dreams

I keep having dreams with people who were good friends of mine when I was a little kid or with places where I lived. I wonder why this is. After all, it's not like I've got any interest of talking to these people ever again or visiting those places in a near future or ever. Maybe deep in my mind I want to return to that safe haven that I thought I had as a child. Anyway what'd Sigmund Freud say?
