Possession of hannah grace
The Haunting of The Hill House.
The Nun, Conjuring, Anabelle
The Curse of La Llarona, The Nun, The Exorcist, The Haunting of Connecticut part 2, Insidious all 4 parts
Lights Out! Scared the crap out of me
Conjuring is a good one but you should watch Hannah Grace as well. Mama is a fantastic movie in it's own rights.
