I have dreams of I don't know if they're imaginary and unreal people or actual real life people, but I've never met them. They're usually stories having to do with celebrities, spies, ninjas, and all that fantasy stuff. I'm not usually in them...I'm just watching it...I guess, like my dreams are TV shows.
Is it normal? Does anyone else have this? What does this mean?

It's the individual dreams that have meaning - and everyone here has wished that that meaning was easier to decipher! Dreams can include people you know and people you don't. Sometimes, as you've seen, doing fantastic things.

In time, if you pay attention to your dreams and perhaps write them out when you wake up, you may find you're no longer a spectator but one of the characters. In fact, you're the star! Problem is, you're the only one who doesn't know the script!
