I used to never dream but I would go to bed with the TV on. I wanted to switch to falling asleep to music. At some point I realized I would have nightmares whenever I slept without either. It was like my brain couldn't handle the lack of external stimuli.
But I wanted to dream more, so I started going to bed without it more and more often. Eventually those nightmares turned to dreams as I pushed through it. It was fantastical. Almost like hearing music for the first time after being deaf. It was a whole new world and I can't get enough.
