I didn't know where to put this. I hope this is the right place.

There is an evil spirit that lingers in my room and certain places of my house. I'm worried that I can't let anyone in my room because of this spirit.
It speaks to me in a foreign tongue and I can't decipher what it's trying to tell me, but I know it's evil and I'm worried that if I let people into my room is will destroy them.

I have been trying to avoid this spirit as bed as I could, but when I sleep at night it bothers me and makes me feel sick to my stomach and turns the room into a very scary place!

This might be a really stupid question, but how can I get this spirit to leave my house? How can I get it to stop haunting me and how can I get it to stop speaking to me?
