I've had this problem multiple times. A psychic said that the spirit follows me and has nothing to do with where I Iive. If it doesn't bother you, just ignore it. It used to scare the crap out of my ex girlfriend and her daughter and I would just go out to the living room in the middle of the night and ask it to stop scaring the girls. It normally worked for a few days
I know you don't want me to tell you this, but your house isn't haunted - you are. The reason you are haunted is because you are mis-interpreting the things that happen to you. You see things out of the corner of your eye, or seem to notice things have changed position overnight, or you hear creaks and rattles, and you interpret these to mean the house is haunted, rather than the normal things that go on in life. I've had this experience myself - I was once half convinced a house was haunted - doors open that were closed the night before, pools of water on the floor, fire alarms going off for no reason. Then I took hold of myself, and found that the door would do that if not closed securely, the pool of water dripped out of the fridge door when it was open, and the fire alarm ALWAYS went off if you left the bathroom door open while showering. So, become less sensitive, more realistic, and voila! Ghosts gone!
This is the Truth as presented in the Holy Scriptures - there was a war in Heaven and the rebellious angels were thrown out. Eve opened the secret door in Eden and let them onto the earth to spread their rebellion here. For entertainment they frighten everyone not protected by the good angels of God. Read Psalms 34:7 and believe.
