You almost certainly do too, but the part of our brain that commits things to long term memory is inactive when sleeping. When people recall their dreams, it's at best just the ones that occurred right before waking up. Maybe you're a heavy sleeper and tend to sleep through that window.
Also why people tend to not dream if using substances that have memory loss side-effects—weed is common. And same reason people get "black out" drunk or drunkenly repeat themselves. The brain just isn't noting anything down, but it is happening.
As far as I know, everyone dreams every night...it's part of the sleeping process...but you usually forget it ASAP so it seems like you didn't dream.
As for dreams I remember...less often as I get older, I find. Although I do get a few vivid dreams when using magnesium supplements, but I also acclimate to those quickly. And if I'm woken prematurely, sometimes a dream sticks around a bit more than it otherwise would.
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.
I usually have three or four dreams a night. I often wake up thinking I should write them down as plots for short stories. I've sketched out a handful of the really far out ones (like when Colin Farrell popped out of a statue in front of a frat house to warn me that Bill Gates was chasing me).
I really haven't had dreams in years. I used to dream regularly in high school, and would regularly experience dream deja vu irl.
I thought maybe it was due to my appreciation of cannabis, but I only had one dream during my last T break and it was early in the time period. No other dreams over the course of multiple weeks, so idk.
I dream multiple dreams every night. They go from nightmare, to straight up crazy. Some are vivid enough to feel real, and some are so fucking crazy that I know I am dreaming. But I have never gone without having one.
Even at 5 years old I a recurring dream that was a tv series staring me. To this day I can recall those dreams vividly as if they happen last night.
I dream often, usually I am able to remember them if I want to but never really bother unless it sticks out as a great story. It tends to happen when I'm about to wake up and while I'm in that mid sleep twilight zone. (Think of trying to back to sleep after an alarm, that kinda sleep)
I would also like to mention that my sleep in incredibly messed up. I have a sleep condition that causes me to wake multiple times an hour so my rest is awful and I'm eternally exhausted.
I've found that I dream a lot, I just forget quickly, which can feel like not dreaming. For a while I kept a very light dream journal, just writing down whatever small thing I remember, even if it's just a feeling or something super vague. Don't worry if you don't remember anything initially — just being in the mindset was enough to boost my recall. Key is to do it right after waking up, while you're almost still half asleep. Write on paper with a pen, not your phone — it's too distracting.
During that period I remembered multiple dreams each night in full, and the memories were incredibly vivid, sometimes almost lucid. It was honestly crazy — some of those dreams had elaborate storylines, often super interesting scenery, and sometimes even almost video game-like "mechanics". I can only recommend keeping a dream journal... you learn a lot about yourself.
I dream every night. I even dream frequently while taking naps, sometimes as short as 15-20 minutes.
Many dreams I forget shortly upon waking. As in, I can't remember what it was about by the time I get out of bed. But, I do actually remember the dream for a few seconds, so I know it happened. The majority of my dreams I can recall for the rest of the morning or even day. If something noteworthy happened, I can remember the dream for days, weeks, or years. I really depends on how impactful/meaningful the dream was.
I have not used sleep journals or anything of that nature to help me remember dreams. I have always been like this. I also have had sleep paralysis and sporadic insomnia for about as long as I can remember - not severe or frequent enough to need treatment.
