I don't dream. No nightmares either. I have no problems sleeping and I'm not on drugs so it isn't a health thing - I've been like this all my life.
The only times I've managed to dream are when I nap while already well-rested, but even then I still usually don't. Like I might get 1 or 2 dreams a year in total from when I go back to sleep immediately after waking up, but never from normal sleep.
Hmm, usually not. Like 90% of the time I don’t remember dreaming at all. Maybe like 7% is that I remember the dream because someone IRL was yelling my name and I somehow added a character in my dream that yells my name, then I wake up. Maybe 3% of the time I can remember my dreams naturally. I used to write in a dream journal to describe my dreams the second I wake up, not anymore tho.
