I think we all dream but just don't remember, that's what I've read at least. LOL! I saw a post once that said: "When you see a toilet in your dreams, do not use it!" - I do agree with it hahaha or you might risk yourself peeing on bed :P
Oh usually lucid dreams are fun! Cos you can fly, jump high, punch random people, become anything you want... Well, I do understand you're afraid and I certainly don't wish this to happen to you.
Speaking of which, I've had dreams of me Steeming as well. Or chatting in Discord hahah. So this might just be your dream as well :P
