In the world of dreams, you can do anything. Sadly, since few of us are able to know we're dreaming when it happens, those powers kind of go to waste.
However, lucid dreaming, the scientifically-confirmed ability to control your dreams, occurs when a person realizes they're asleep. Once you do, you can experience just about anything you wish. We'll let you come up with your own ideas about what that might be.
Though some people are more prone to lucid dreaming than others, it is something that can be learned by applying techniques to make yourself aware of the fact that you're dreaming. Give these a try, and have fun doing whatever it is you've always wanted to do. Again, we won't elaborate. Or judge.
