If you want to get rid of a troublesome ghost the thing to do is create the thoughtform of an imaginary house and somehow persuade the ghost that it's where you're now living. It will then go and haunt the thoughtform. Being immaterial itself it's presumably unable to tell the difference.
The particular ghost we were trying to shift was that of a killer white rabbit- very like the one in Monty Python and the Holy Grail. We decided for added security that we'd site the imaginary house a long way away from our actual one- specifically in Birmingham.
