If I could completely shut off dreaming, I would.
I have always had far more bad dreams than good/neutral ones.
Even some of my neutral dreams turn bad in a way, where I walk around seemingly for hours (even if it's not really hours) looking for something or someone I can't find.
Good dreams are very rare for me. I had one last week. The dream jumped around to a bunch of different scenes, but all of them were fun. In one of them, I was a player on the Lakers.
I actually have fewer bad dreams now than I used to.
I never have sex in my dreams. Something always stops it from happening.
