How rare is this?
I've been able to control myself in my dreams for as long as i can remember, and thougt it was pretty normal and everyone could do it!
I've never manipulated the world or anything though, i didn't know it was possible to do that in a dream, until today.
Everything was normal, until today.
I've simply always had this talent, i even met my friend in my dream and spoke to him!
I never talked to him about it in real life, though, i didn't know that was possible either.

So that question is as reads: How rare is this?
How long do people have to train in order to access lucide dreams?

Edit: I almost never have to perform reality checks either, i just know that i'm dreaming as a reflex, and i tell the people around me.
I want to kill myself for not realizing that i can do whatever i want, hopefully i will dream tonight.
