Halloween // Movie recs, please

I am going to be alone-ish (MIL and BIL will be her, but in their bedrooms) this Halloween, therefore I am going to watch as many movies as possible from the time I wake up until I need to go to sleep. I have a few staple/favorite movies that I watch every year, but I want some classic or even b movie horror films. so far o have the classic chucky movies and the classic Halloween movies, oh and scream. any others I absolutely must watch?
