Ghosts That Still Walks. 1977.
This one I have never heard of so went into it not knowing what to expect and seems to be a rip on The Exorcist, Exorcist II and drop in a bit of The Manitou (that was released a year later)
We have a 15 year old Mark who is somehow possessed and living with his sweet old grandma who are both under psychiatric care and the doctor uses hypnosis to understand what exactly happened to the family.
So don't expect a priest to turn up and go full blown exorcism on the possessed lad who has been possessed by a Indian medicine man after Mark managed to have a outer body experience. Most of the film is shown in flash backs. This is very low budget and seems to use the same part over again in the runaway camper home sequence. The acting is not the best but not the worst. Maybe a re-watch will happen at some point.
