I notice a pattern of certain dream categories that are common to a lot of people.

I am very curious as to why these are. Here are the ones I have noticed so far. Feel free to add to the list, and discuss why you think certain categories are common. What is interesting to me, is a lot of these dream themes are not common occurrences in waking life.

Flying Dreams

Teeth Falling Out Dreams

Naked in Public Dreams

Being Chased Dreams

Killing Dreams

Outer Space Dreams

Geometric Shapes Dreams

Battle Dreams
