I've had some dreams kind of like that before. Where you have a power and you think you actually have it. It's cool that you were so suspicious that it was a dream. I usually just think I'm the next superman or something and I just go around and show-off.

It's also way cool how your mind seems powerful enough to make the reality checks work, although I would think that would make it harder to become lucid.

In my experience, I've learned that no matter how vivid and real my dream is, if I do, or see something impossible, I know for a fact that I must be dreaming. None of us have ever seen anything impossible in real life other than magic tricks, therefore, when it happens, we have to be dreaming.
