Recourring nightmare/dream

I have this reoccurring nightmare/dream that keeps showing up (i say nightmare/dream because I wouldn't really call it scary just mildly upsetting)

In the dream im always back in school, usually highschool but i think I've had one or two where i was in college (i could be misremembering idk) but every single time in the dream i get so anxious and worried because i can never remember what or where my classes are, and i always get even more nervous because its in the middle of the school year do it wouldn't make sense to go ask for help because why wouldn't i know what my classes are, so i mostly bumble around the school trying to figure out the order of my classes and everything. 

Usually it'll end up with me just winging it, going to a class i think might be right. I've had this dream so many times and I'm so tired of it, I don't need to deal with school anxiety in my dreams(⁠￣⁠ヘ⁠￣⁠;⁠)

I've googled it and i think it just means I'm generally nervous about things in life? If anyone has another interpretation I'd love to hear it

Another dream I've had more than a few times now is one where im pregnant, they kinda vary alot, from ones i remember there was one where i was pregnant with an alien, another where i had chicken eggs and had to lay them (i got weirdly attatched to those eggs i was upset i didn't get to see them hatch because i woke up lmao), one where i had a baby and it turned into a cat, and a more recent one where i had a really small baby and i fell into a post partum depression (i was so annoyed when i found out the feelings in that dream was post partum depression literally why did my brain make me experience that💀💀)

Google says it means big transformation and big changes or whatever, but it doesn't feel like I've experienced that yet so idk
