Dreams about conducting exercisms! HELP HELP HELP?

I've had dreams about fighting off possession since i was a child. I do believe that my last home was excessively haunted though, more than any other place i've ever been in my life, because i would get what they call "sleep paralysis" two or three nights a week. This figure would manifest above me, talk around me, and even sometimes touch me, the entire time a would cling to my faithful lord. I also had vivid dreams, dreams of this thing talking to me, trying to take me from god through possession ect. One night i dreampt of my great grandmother, this thing told me to "inspect the crypt, there is still fresh blood within the ." and other unsettling things among that nature, which disturbs me, being a christian i pray my grandmothers soul is safe with god. Since a young age i've experienced stuff like this though. More recently through the years i've had dreams where i conduct exercisms upon people i love, my sister, boyfriend, even my kitten once, whenever these things try to take me or a loved one. I would like to know what that means. I have made peace with the nightmares, i am strong enough through gods love to each time these demons or whatever they are try to take hold, i send them away through exercism. I would like to know if anyone else out there experiences stuff like this. I am sound of mind, i feel a little more perceptive towards whats around me than others though. Mostly though, i wanna know what it all means. I don't actually attend church, should i consult a church? Is it a sign from god, that maybe this is my calling? Someone please help me make sense of this, i feel like maybe an outside outlook of the situation will help me. Thank you very much, and god bless. =-)
