Need advice for a friend who's possessed. No history of psychosis or anything. He's started seeing dead people and entities after lots of hardcore meditations/kasinas. That's fine. But then he invoked Kilindi lyi and he won't leave. "I invoked him for sexual reasons. I wanted him to be my son. But then he started disobeying me, and has sexual powers over me, ie. can give me erections, and he claims to be able to do it over other people too, in ways that are distressing to me. He wants to have sex through my body, and I don't want it. It is distressing. He speaks in a clear voice and has overriden my internal dialogue, and he appears embodied in the room against my will, everyday for weeks now."   What do y'all suggest?
