Imagine you're watching a movie, but in this movie, you can control what happens! You can fly, talk to animals, or even visit your favorite candy land. That's kind of what a lucid dream is like.
It's a dream where you know you're dreaming. And because you know it's a dream, you can sometimes change things in the dream and have a super amazing adventure!
It's like being the director and the star of your own movie, but instead of happening on a screen, it happens in your imagination while you sleep.
Isn't that cool?
Many people learn how to have lucid dreams. They practice things like remembering their dreams and asking themselves throughout the day, "Am I dreaming?"
