i could use a a lot of help!

[etereo]

there been some wierd things going on my house for 1 year now for instances my girlfriend getting the thinnest scratches on her while she is sleeping these arent human scatches one stratch was even the shape of an A, my laptop moving from one place to another while im sleeping, feeling the lightest touch on my bum before i go to bed, small hand marks on the window after a snow storm when there is condensation on the window and i havent even touched it . They where too long to be my girlfriends hands and way too small to be my own. Another thing my girlfriend seemed like she was possessed while she was sleeping by this being she wouldn't wake up for the life of her, i told her to wake up multiple times but she wouldn't and she was very angry at me when i tried to wake her up her eyes where rolling around like the exorcist. My girlfriend doesn't remember these things happening to her. Also i smell things that aren't there, i am not a paranoid person. I smell smoke for two seconds and then it goes away. on the side not i am a man of god a i pray to Him when i need help He answers my prayers. I love Him and he loves me. I wear a crucifix everyday and i also wear it to bed. Please stop questioning wether god is real or not on these forums even if you put a million dollars worth of research you are still not gonna prove that god exists or not. Can someone please help me get rid of this being in my house it has caused me a lot of pain and suffering. thank you and god bless to everyone that helps me
