I think if you look around you can find some one to kick out your ghost . You might try some of the standard stuff , like telling the ghost there dead , its time to move on , go to the wite light , hell is just a myth , ect. You can do a smudging . There is also the possability that this is a human created thought form . We all do this to some extent . There are methods to clear out thought forms posted on the net . They are selling stuff so I wont post links , but there easy to find . I will give you my fev. search site .
