Oh, this is a fun thread. Since I was a kid, I've had extremely vivid, often lucid dreams. It can be very disturbing when I don't realize it's make-believe right away. It's only when unrealistic nonsense happens that I realize it's a dream and I can have some fun with it - ie. I'm flying again, there's zombies, I'm killing soldiers, etc.
It sometimes happens a couple times a week, but there can be weeks and months between such occurrences. Seems to be really random. I remember a lot of it when I wake up, especially when I am shocked by a horrific event into wakefulness, and I grab my phone and jot it down in my notepad before it goes away. If I go back to sleep again quickly, it's usually gone forever.
I've used these strange experiences in stories over the past couple of years. The original ones, anyway. There are often these recurring themes that aren't very creative or interesting, involving trying to navigate architectural mazes like airports and shopping malls and never getting anywhere. Trying to find a place to pee (

), a way to get home, avoiding getting involved in crime/violence that I am observing, that kind of thing. Always a relief when I remember that I can fly and yeet myself outta those situations.
The rarest and most shocking ones which always result in a sweaty, instantaneous return to consciousness, is when I am killed or am about to be killed. One that I'll never forget from my childhood involved me hiding in my closet, feeling and hearing these bombs being dropped, closer and closer, louder and more intense, clearly being dropped in a line in my direction. And the last one that hits blows my bedroom apart and I can feel myself on fire, burning, dying, and then BAM I'm awake.
