[TOMT] [MOVIE] I need help finding a movie i keep dreaming about

It’s a horror comedy movie about a group of (i think) college kids at a halloween party or something, then there’s some evil magic thing that happens that brings a bunch of monsters to life that proceed to kill a bunch of people (maybe the college kids don’t become privy to it immediately and think it’s just some halloween tomfoolery) but when they eventually become aware they start running around town trying to reverse everything, there’s an ongoing conflict between a couple of the characters, a couple of em get killed, they kill a couple monsters by unconventional means, but in the end they figure out what to do and reverse whatever magic and everything goes back to normal. like the way it was before all the monsters normal, everybody’s alive again and they’re at the halloween party (maybe the morning after the party) and they’ve learned some sort of lesson because of their experiences.

keep in mind this is a horror comedy, and it’s an absolute bloodbath of a film, i know this isn’t a lot to go off of but i can’t stop thinking about this freakin movie i’ve dreamt about it so many times.

i’m not sure how recent the movie is, but it’s not too old and it’s not super recent either, im thinking like early to mid 2010’s but i could be mistaken.

please god help me find this movie i would ever so greatly appreciate it!!
