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.

Do you really have dreamless sleep or do you simply not remember the dream?
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.
It wasn't dreamless, you just weren't remembering your dreams. If your sleep was truly dreamless for a lengthy period of time you'd be dead.
Often simply changing your sleeping habits in any significant way is enough to get you to start remembering dreams. That's because you need to wake up "unexpectedly" in the middle of a REM sleep phase to have a chance to form memories of them. Normally your brain has its memory-forming mechanism disengaged during REM sleep because there's no good reason to remember that stuff - it's just a side effect of a mental housekeeping routine.
You can also "train" yourself to remember dreams more often, to some degree, by trying to record a dream journal or otherwise forcing your brain to lay down some memories of those dreams the moment you wake up and they're still present in your short-term memory.
You're not supposed to remember your dreams. When you remember your dreams it's when you were woken unexpectedly, or when you consciously or unconsciously fled the dream before returning it to the Dreammaster.
We only borrow our dreams from him every night, but when we leave a dream prematurely we are stealing that dream - bringing it into our reality and hiding it away in our memories.
However precious or horrid your stolen dreams may be, remember that the Dreammaster will claim them back from you. He always does, in the end.
Thank you. The only scientific answer in this thread.
I for one welcome my sleep overlord.
