Some people can have a few dreams in a sleep for consecutive nights.
Some others, (I'm part of them too) don't dream often- perhaps once every few months time.
But, dreaming may be a bad thing too.
Besides fantasizing, a dream may be horrifying. For example, dreaming of your girlfriend flirting with some other guys; or, dreaming of your dick get cut off by something when steamed.
Anyway, it may be fun too. I have a friend who was a SERIAL KILLER in HER dreams. Haha. She'd killed numerous number of people in her dream... horrifying? Nah, sounds exciting.
But that's not the case for me. (almost) Everytime I dream of something - it wouldn't be a good one. It's always traumatizing... Urgh, damn scary.

Ooh ya, oooh! Ooooh!! ooOOhh YaaaA!!!
