So when I was little there was this clown or a spider maybe that would terrorize me and my friends then my one?

friend had called me up and said that another friend of ours is dead and we all need to go back to the town we grew up in and fight the clown spider things ( we just it it ) and so were here to kill it but all kinds of weird things are going on like blood everywhere on the mirror and stuff. What should I do?
