A couple years ago I had this dream that I was going to this boarding school on "Vancouver Island." In quotation marks because the island looked more like the one that the Dursleys moved to in the first Harry Potter movie. The only way to get there was in this rickety boat and it was super stormy so there were huge waves, but that wasn't really the scary part. Every now and then this spider would run across the room and it always sent everyone into a panic (like, people would stand on tables so they wouldn't have to be near it).
Every time the spider came out it would get bigger. The first time it was slightly bigger than a daddy long legs. Second time it was more the size of a tarantula, etc. The final time it came out it was like the size of a small dog. For some reason, the last time it came running out it came right at me, and for some reason I couldn't moved and the spider jumped up to my neck and somehow had me pinned to the ground. It started biting my neck and a bunch of people were just standing there watching it happen.
When I finally woke up I still felt like the spider was on my neck. I'm terrified of spiders this was like the worst dream I ever had.
Also, I wasn't going to bring these next to up but since @Cloudy-On-Quarantine and @"betsy.cant.write" mentioned school shooter dreams so I guess I'll share mine.
I've had two school shooter related dreams (and I've definitely mentioned at least one of them on another thread). But basically, the first one I was in the library in my elementary school with my friend and suddenly we went into lockdown but some kids wouldn't stop talking so the shooter heard them and came in.
The shooter in this dream was a Japanese girl dressed in cyberpunk style clothes and she was super giddy. Like she kept giggling, clapping, and jumping up and down. It was so unsettling. Anyways, she started doing eenie meenie miney mo to decide on who she was going to shoot first. Don't remember who she landed on, but I woke up before she shot anyone.
The second one started out like a typical weird dream, then got super dark. I was the teacher, and my classroom looked like the treatment room at the vet clinic where I was working (all the kids were sitting at treatment tables instead of desks, and my desk was the dental table). I was teaching the kids about animals and for some reason bought betta fish for each kid to take home.
I was handing out the fish when there was announcement that there was a shooter in the building, but the shooter came into our class before we had the chance to do anything. The shooter in this dream looked like the hearse driver from the movie Burnt Offerings (Which is a super old movie. I've only seen part of it, but the hearse guy still haunts me. Here's a link for anyone who wants to find out how unsettling that is. There's no jump scares here, it's just really creepy imo).
Anyways, this shooter came prepared with a list of students that he wanted to kill which is super fucked up because they were all like grade 1 or 2. He called up the first kid (I don't remember his name, but it was super weird and I remember thinking it sounded like a drag queen name but that's not important).
I start freaking out because I'm the teacher and I can't let my students get shot. The shooter is trying to coax the first kid out of his hiding spot (we were all under the tables) and I had this weird thought where I was just like "stay calm, you've been through this before." And I don't know how I knew that was a reference to my previous school shooter dream, but I did and then I had this other thought were I was like "If you wake up now, you can save everyone."
And so I just like, woke up? It was really weird, but I woke up from both dreams feeling super terrified.
TLDR, I had a dream where I was attacked by a giant spider, + 2 more school shooting dreams the second of which got really weird and meta towards the end but was still terrifying regardless.
