From how I understand it, you dream every night as your body enters REM sleep, but you often don't remember dreams. You can try and train yourself to better recall your dreams and in doing so you may find that you "dream more often".
I'd say I have weeks where I remember my dreams, sometimes multiple, every night, and other times where I'll go a week or more without recalling any. It varies on a lot of things. In particular, I'll find if I stop smoking weed for about 4 or more days, I'll start remembering dreams vividly and frequently, but that'll lessen over 2 weeks.
Yeah, everyone dreams multiple times every night. I'm sure these days most people mean 'don't remember dreams' when they say 'don't dream', but when I grew up so many people honestly thought they did not dream and wouldn't believe me when I tried to explain how that's biologically impossible.
The bigger issue IMO would be that not everyone has quality sleep, so they might not have a long uninterrupted time in REM to properly dream.
Personally even when I'm in the right state to experience dreams (the type that I do remember) they usually aren't very vivid, for the above reason or possibly something else. I also have aphantasia so it may be related (or other brain/life stuff). Once I did have a colorful-yet-still(ish) dream related to then-recent photography.
I dream all the time, and always have. There are often common themes, eg., searching for my wife, yet she's never actually appeared in my dreams (that I recall.)
My departed parents often appear (moreso my dad, recently), and 2 days ago, a recently-departed SIL appeared, though 'visually', it wasn't her.
I'm not sure of whether there's a significance to any of this. It is what it is.
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.
Multiple times a night. Typically I know I'm dreaming and can choose to wake up or alter the dream if I like, but I have some "uncontrolled" dreams as well.
Yes, every night AFAIK, but I sleep very deeply and seldom remember them beyond a matter of seconds. If I've had caffeine late, I do tend to remember them more.
I dream every night and it is always some kind of a crazy bizarre acid trip that may morph into a nightmare on occasion if I had a bad day or something is weighing on my mind. I've had this all my life and sometimes when I don't dream (which is extremely rare for me) it feels weird waking up.
But that's the regular stuff, the insane stuff is that I have dreams that reoccur and evolve for decades, and it's like getting a new season of a show that you watched two years ago, but with new characters and plot lines.
Do you use an alarm clock? The best way to remember your dreams is to be startled out of them and immediately thinking about them. If you wake up without an alarm clock and then start thinking about what you have to do later in the day it's gonna be harder to remember them
I wouldn't say I don't dream, but for reasons relating to birth, I dream in any substantial way very, very infrequently, and if I do, it's momentum for something else. I only ever remember dreaming in three topics: school, browsing, and talking to people I miss, with an infrequency of once a few times of year each. What few dreams one could say I have I care so little about that I often do everything I can to make sure I won't dream. I just don't want to be teased by having happy dreams that then say "psyche" and remind me of the state of being I'm in.
