Sleep Apnea Treatment

I suffer from R.I.S.P. (repetative isolation sleep paralysis) in which I see images of people and animals in the room, I also here music sometimes like a radio is on. My theory is this that many people who experiance ghosts have an I.S.P. (Isolation sleep paralysis) When it happens to me I know it’s my sleeping disorder that makes me see the images in the room. So has a study been done to link ghost sightings with I.S.P or R.I.S.P. ?
