I had a dream where I came back to college, but it was a bit different. There were some students I recognized from the previous semester, including ███. I was going to go to some typical art class until I saw there was a vampire class/club, so I joined there. Some of the people there, including the teacher, was a vampire!

I had a dream where everyone wore masks while traveling outside because they thought that we’ll die if we don’t.

I dreamt of becoming friends with visible germs and later on had those germs trying to kill me because I stepped on one of them in school.

I had a dream where, at the end, I was running (possibly running away from something or someone?) and accidentally fell down into a lava pit. Right before I touched the lava, I woke up, and while doing so, I caught myself falling off the bed!

(I'm debating if this was a dream or just an idea that was scaring me back in my pre-school days, but I'll add this here just in case)
I had a dream(?) where I was at a room (likely my bedroom) and an asteroid as approaching towards me. But right before the asteroid hit me, it notably had a window showing a green (or purple?) alien being smug (flirting?) with me. After possibly having this as a dream, it freaked the hell outta me and i couldn't stop thinking about it for at least a year.
