The only dreams I usually remember are nightmares where I die in the end so not exactly pleasant, but they do tend to be very interesting.
One of the most bizarre honestly felt like some chaotic, unhinged video game concept. I don't remember how it started but I remember going through what felt like minigames with one having me frogger down a river. Somehow I ended up in this abandoned town chasing a girl who seemed to be the only person around. I go down into the woods looking for her, she goes after me telling me to run and get away from the forest, and then these dark creatures with a bunch of hands grabbed me and whoopdeedoo I got dragged into the void or something.
There was one pretty short dream where I was walking through a library with some friends and there was this raffle bin where you could write down your favorite book on a slip of paper and you could win a prize. That part was oddly specific. I walked out with my friends and, what do you know, I had traveled through an extradimensional door and I was now alone in a giant, run-down maze of a building. After nearly going insane trying to find my way out, I finally found a door but outside the door was a steep drop off into the ocean and all I could see were the massive walls of the building that seemed to go on forever on either side of me.
And then there was one where I was getting ready for school in a dream. While I was brushing my teeth, I went to spit into the sink and when I looked up and into the mirror I saw the grim reaper standing behind me. Then I woke up and had to actually get ready for school with that fresh in my mind.
Oh and there was one where a Nomu (like from My Hero Academia) was in my house and trying to kill everybody and someone I'd never met was helping fight it off but it still got me. That dream Nomu was terrifying.
