You know your tolerance; I know my movies. Here’s a complete breakdown of the three levels each movie is ranked upon by scariness:
😱 Level 1:

Spooky—so suitable for novices or those who watch most horror movies through their fingers, though some mild hiding may be required. If you don’t scare easily, you could get away with watching these solo—even before bed, if you’re a freak like me.
😱😱 Level 2:

Scary—but not utterly terrifying. Sure to disturb (if not frighten) those with intermediate horror tolerances. They might be a little too intense for those who scare easily, but are recommended if a scaredy cat is feeling extra brave and wants a rush.
😱😱😱 Level 3:

Horrifying—a real treat for horror aficionados and satisfying for those who are numb to fear. Those prone to nightmares post jump scare may be at risk for some light trauma.
