Consciousness is often said to disappear in deep, dreamless sleep. We argue that this assumption is oversimplified. Unless dreamless sleep is defined as unconscious from the outset there are good empirical and theoretical reasons for saying that a range of different types of sleep experience, some of which are distinct from dreaming, can occur in all stages of sleep.
For a long time, mine was dreamless. It wasn't until I turned off the TV before going to bed that I started to have dreams. I theorize that the external stimuli hindered my brain from creating dreams.
It was a super weird period because my dreams started as nightmares, like my brain didn't know what the hell was going on. Then I drifted through a period of recurring dreams and then lucid dreams. They've settled down into more normal dreams, but I'm still super excited to dream each and every night. It feels like I found music after being deaf or seeing colors for the first time after being blind.
