I remember parts of my dreams often throughout the day, and when I first wake up otherwise I just forget them until I get another clue of a reminder of my dreams.
My dreams are usually about whatever is going on, or once events end, basically all about that. I usually dream about pets escaping, bad things happening to them, or really random things. Last night's dreams were clearer than usual so I remember that I dreamed about bees everywhere - trying to escape them which reflected me saving a bee earlier yesterday, and something about my dog dying although don't know how that relates. Sometimes in a dream I'll realise I dreamed it before but not know I'm dreaming when I probably dreamed it earlier in the night and never before. Though sometimes certain dreams do have locations which repeat in different circumstances. I can think of a few dreams off the top of my head where I was in this city and bad things were happening. Then there's stuff which relates to games I've played (usually Mario ones), or other things - like how I sorta dreamed about B2/W2 yesterday (aka not last night) or just remakes of Pokemon games which are more realistic and amazing and I wish were real. :(
Interestingly I used to dream about PC a lot before I got modded but now I barely do, so hey if you dream about PC too much, get modded - totally the cure!
But yeah I can remember standout dreams well, usually I've been having lots of fillers though, so yeah. I also dream about spiders a lot (aka big fear) and the house being robbed - which helps me remember that the two nights before last night and yesterday I dreamed of being robbed and nearly shot, and then just being robbed. Oh yeah, and being late, defs something that occurs often. Also end of the world type things, like omg the amount of times the world has ended with my dreams, lol. I remember there was a war, then something where you lost your bodies, then suddenly a big ocean, etc (all different though). I tend to not really pay attention to my nightmares anymore unless they're so realistic that I end up scared (all of those mentioned sadly didn't really scare me sadface).
