Last night in the astral plane I noticed I had a large black mark in the center of my chest. A man was there, telling me I needed to see a doctor to get help because I was sick. I am wondering if this might be a sign of black magic or from a witch? I read on the website that black marks on your physical body could mean that someone is using black magic against you. Could a mark on your astral body be similar? Thank you for your help!
