We had a ghost in this house for a while after we moved in to this house. He only haunted me though, my dad never was affected by it. He would come in, walk up the stairs and lay on my dad's bed. My dad has had the same mattress for many years, so it's got a very distinctive set of squeaks to it. The floorboards on the stairs creak as well and are right outside of my room.
Every once and a while I would find the front door open, and the cupboards in the kitchen slammed shut while I was in there. (PS our house is practially airtight, not an old drafty mess that would cause the door to blow open or the cupboards to blow closed.) And I would also wake up at night thinking someone was in my room... either I would hear a noise and wake up, or just feel like someone was there and wake up from it.
After a while, I talked to a friend at work about it because I thought I was going nuts. She's into all the ghost/occult/witchy stuff, and she suggested I just project a space away from myself and ask the ghost to respect that space, nicely.
I haven't had a problem since then, so whether it was a very polite ghost, or just the power of my mind setting itself at ease, I would suggest trying the same with your ghost.
ETA: But I also have extreme issues with deja vu, so perhaps I'm also having seizures and not aware of it.
