Is it normal to really cry when you do in dreams?

Once, I cried, almost choking, among the crowds because I was made fun of (I can't remember clearly though, it happened like 2 years ago) in my dream, then when I woke up, I WAS literally crying. I actually thought it was really .. cool to experience that kind of thing..:O I was amazed haha
Then it happened again like just now, I cried because my dad hurt me. Bad. But interesting thing is that I cried over what I was worrying about..twice. I mean, 2 years ago I had social problems and recently, cuz my parents are not getting well, I have family problem. Is my dream showing my subconscious worries?? But for what?; I don't really feel better after the dreams..... Um.. Sorry for my bad English
