I have a giant shadow spider that descends from the ceiling onto my face all while I have the stuck in the mud feeling.

Teeth. Hasn't happened for a while but there was a time when they were always growing or falling out.

I hear it's pretty common.

Suddenly realising I'm naked. Like I'll be going about my day, everything is fine, then I'll look down and "Oh no, I forgot to get dressed!".

I've obviously never done this in real life.

I'm nearly fifty, thirty years since I last did a school exam, and I still have recurring dreams about them. Weird, because I didn't have any stress or anxiety at the time... at least not conscious stress.

My dream takes the same basic form as yours. I am approaching a time when I know there should be an exam, but I haven't been to the class at all for the year. Mostly the dream consists of me hoping no-one will mention the exam and I can just kind of pass it by default. It makes no sense.

Other recurring dreams:

• I stumble on a previously unknown room in my house
• My Grandad, who has been dead over 20 years, is suddenly alive again. Everyone knows he should be dead, no-one really mentions why he's alive again, and there's a weird feeling that he's hanging around on borrowed time.

Getting ready to do something exciting, but being held up by something trivial.

For example, I'm about to go on holiday, but I can't find my car keys. [Spoiler - I never find them and I wake up without having been on holiday ]

I have a very similar dream to yours, where I don't even realize I'm enrolled in a class until a week before it ends. The main difference for me is that it isn't an exam that I have to get through. Instead there's some kind of year-end assignment that is due, which requires me to know everything that has happened in class all year.

Another, scarier one that I have is going into the basement and once down there, the stairs to get back up are gone. So I'm panicking trying to find a way out (and sometimes chased by a monster).

All of my dreams are freaking random weirdness. if anybody wants to spend some time analyzing them, my most recent one, the most memorable thing was some weird russian dude trying to get me to try some disgusting looking frozen "Borscht-Chessie" pizza.

only thing I can thing of is I was reading something about the Ukraine war before bed... and had frozen grease on a shingle pizza for dinner. (that was pepperoni and I added some spicy pickled red onions to it.)

Fighting with my relative with a visceral anger and a sentiment of guilt that follows me long after waking up.
Maybe a way for my social anxiety to catharize my fears.

My reoccurring nightmare is being surrounded by a swarm of bugs. It’s usually wasps, but it can be other stuff too. It always takes place in my childhood bedroom. I always clamp my hand over my mouth because I’m afraid if I scream they’ll fly in my mouth. But I always end up screaming and they fly in my mouth and I wake up.

I’m not sure it has a very deep meaning to be honest. When I was a kid part of my room was a finished attic that was connected to our real attic which apparently had a very bad wasp nest. Everyday during warm months I’d find one or two in my room and have to deal with them. Now that I don’t live in a place with bugs I don’t have this dream anymore.

I had a really weird one when I was a child. I would be chased in black abyss by a giant sword which would then drop on my chest. I would wake up feeling a stabbing pain in my chest and the coldness of the blade. Usually I would fall back asleep and have a similar running dream, this time falling off the abyss and waking up suddenly again.

I also have high school dreams.
It's the first few days, and I'm trying to find my class, locker, or schedule. I can't find them and I know I can go to the office to get info, but I can't find that either. I seem to know where the cafeteria is and use it as a centeral location.

It's not scary, just stressful.

I also usually have the rocket boots from Ratchet and Clank to get through the halls fast. I don't know why that's a constant reoccurring item, but it is.

For years I had recurring dreams where I was lost wandering an endlessly large building - usually office buildings with hundreds of hallways and stairwells that led to more endless hallways. Haven't had them as often the last few years but they always left me feeling down the next day.

I've dreamed multiple times about being back in highschool, being late for classes or not studying for exams. It's almost like it traumatized me lol

I have this dream where an emergency arises and I try to dial 911 on a phone with physical buttons, and the number 9 is just not there. And it's always like, right as whatever is chasing me closes in on me.

I'm running from the foot soldiers from Power Rangers and leaping from rooftop to rooftop. I never remember any of the details but I've been having that one for 30 years.
