Go to the church and ask them to visit your house and bless it, if it doesn't work search for a parapsychologist online. I have seen two ghosts/presences myself personally, first one i was about 8 and it was a military man wearing clothes similar to those used in the yank civil war or to those used by the liberators of The Americas, he was all white, including his clothes, sitting in a chair with his legs crossed i think, one on top of the other and with a mean as fuck look on this face and signalling me to approach him with 2 fingers, i ran for my fucking life and by the time we went back there with my family he was gone. It was at my military granduncle's house and they said they had heard sounds of people walking with chains at night. Scary stuff for sure!
