Absolutely, this is completely normal amongst many people. Depending one's sense of not only creativity but based on one's general thoughts, I think dreams form themselves in different ways. Now, many people I know, who just want to be "normal" have very boring dreams. Dreams that are not different in the least from reality. Wandering around school, fighting with parents.

Now to make a generalisation, the more interesting people I know have more complex and sharded dreams. Some build a very concrete plotline sharded with abstract concepts, but in the long run they're just a bit different.

My dreams in general make absolutely no sense and are just a combination of surreal concepts packed into them. Sometimes (a few times a week, maybe) my dreams will have quite the complex plot that I turn into very fun stories, but in general it's just fucked up nonsense.

Don't worry.
