To start with, I love my brother dearly and am not on bad terms at all.
The gist of this dream is he's asking me to kill him. I'm crying as I do it, but no matter how hard I try, he won't die. He gives me something and asks me to try again, but that doesn't work either. In the end he's just rolling around in pain, and I wake up around here.
These dreams have me waking up very upset with myself. I'm not necessarily asking for advice, just for your thoughts on this.
