Hi there, firstly I’m very sorry to hear about your brother. Though he passed 7 years ago Loss and grief do tend to linger with us and it’s probably why it still manifests in your dreams. Something that day maybe reminded you of him or about death or suicide and triggered the dream to occur. Even though he died of cancer it seems suicide is the prominent thing you associate with him. It’s certainly a complicated and emotional subject and I agree with Darkestdarkness in that I think maybe you’re still trying to understand and process why he once tried to take his life. Maybe you know, maybe you don’t but if it was my own brother I can imagine I would be going through a similar process of wanting to know why and what I could have done to help him. The dream is probably your imagined scenario of if your brother carried out the suicide and you were the one to find him. The fact he was wearing a suit and things felt like a church are maybe things you associate with the subject of death which makes sense.
