That's a load of shit. Every night I make myself have the same dream and I start where I left off the night before. My dreams are also colored and I can control what the people look like, what they sound like and what they do. I can also control myself when I'm in the dream.
I once had this dream in which I was so happy. I was so happy and everything felt great inside of me. When I woke up, I cried and cried because I hated the reality of my actual life. Thankfully, I haven't experienced that again since I left my abuser.
