I am looking for some guidance to help my brother who has slowly been thinking he is being followed by 'dark spirits'. Over the past 10 years he has been involved with faith healing, then conspiracy theories and now thinks that dark beings or beast people are in the bush and out to get him.
This has put a lot of stress on my parents, who live on a region property and he thinks that the beast people are going to attack them. They are getting frustrated with his attempts to scare them, which are becoming more extreme, and he is frustrated that they don't believe him. He is so convinced that the beast people are coming that he has set up cameras and has started to 'patrol' the property with a cricket bat.
I was wondering firstly who I should contact for advice, a psychologist or counselor? Then how do we engage him about his condition. I have tried hearing him out just to keep him engaged with family, but a he cites 'internet evidence' for his beliefs which make it hard to rationalise reality with him. He has also been smoking pot which I definitely think has contributed.
I've always thought he has suffered from anxiety, and perhaps this is being manifested with these beast people. But I am not in a position to assess this, plus how do I start that conversation with him?
Thanks for any advice.
