I have a spirit in my house, and he's an evil spirit, but not quite a demon, I know because I can see, and talk to demons a lot eaiser than I can with spirits, for the past few weeks, I've been having really demented dreams, more than usual.

Like the other night, I had a dream that I was a cerial killer, and I just murdered everybody in sight, for no apparent reason.
I thought it was the meds that I'm on for sleep insomnia, but I looked up side effects on it, and there was nothing about nightmares.

So last night, I lit a sage incense like I do when I don't want him in my room while I'm asleep, and I didn't have a nightmare, or any dreams at all, really.
So I was just wondering if the spirit that lives in my house with me can send me nighmares, and how to protect myself from it?

Please help me out, I'll take any advice that you give me. :]
