My son was meddling with shamanism and now has phycosis,im worried for him .He smoked cannabis and i told him off today and roof tiles flew off my roof outside.Things have happened in my home.This has been going on for nearly 2 years,He says hes a medium as he hears voices and sees spirts.im at a loss what to do.Medication hes on does not stop the voices and the visions he sees.I wondered if anyone eles has had this before.Zooid,Thankyou
