Satanist issues dealing with the boyfriend..HELP?

I hang out with a lot of satanist people. I recently started dating one and he showed me video's on him doing rituals with stuff flying around and they were on his phone so they couldnt of been edited. His one friend was bringing me home and started playing the satanic bible or whatever. After he left i started hearing a lot of stuff in my house and ever since i havent felt right. I've felt fingers on my back and my TV has ranomly been turned on by itself. My boyfriend said its happened to all his past girlfriends he's had feelings for. His one ex Kelli said she woke up with random scratches when they broke up. His other ex Cassidy said it ****** with her head baddd, when she cheated on him. He said to not be scared of it, that its just telling me that it's there. Im still mad sketched out. ANY Opinions??? ~ONLY PUT THIS IN POLLS FOR MORE ANSWERS~
