Horror movie set on halloween help pls
Hey hope you guys can help me with this one (it's have being a mystery for like probably around 20 years to me)
So, this movie had some kind of costume party, idk for sure if it was set on halloween.
There a lot of people in this house (it has at least 2 floors, an attic and an basement)
Theres is a girl who gets possessed some how. A lot of people start to get killed.
at some point there's 2 girls left alive and they try to hide from the possessed one, but she stars to cry their names with her normal voice saing something like "it isn't in me" (I watch it dubbed in Brazilian Portuguese on the tv) and one of the girls believe it and starts to giving their location away.
Unfortunately, i didn't finished so I dont have more information than the pieces i can remember.
I think I remember some guy or guys dressed as bees? And a injection is the thing that got then while they were playing cards? Not sure it's still on the same movie.
I also remember two scenes specifically. One is when some girl (dont now if it is the possessed one) gets dragged from nowhere in the middle of the people in the party and everyone just thinks is a prank. And in the other scene she is getting possessed holding herself to the wall with her eyes completely white.
The movies seems to be from the 80s cause of everyone's hair style.
