Been having some rough dreams lately about my brother. I wrote his wife again the other day, she said "Jimmy doesn't even remember your name, stop writing me!!"

I don't believe that. It's hard to wish you knew your brother, and know that the messages that you send to him are actually getting to him, but they aren't. This is emotionally messing with me. In my dream, he announced that I was his sister without me even telling him. He recognized me in my dream, and he said it was because he saw my hands, and he knew we were the same.
"Hands indicate purpose.
Purpose is the ability to conceive an intention for actions. Intention is important because it sets into motion karma, an indebtedness to Self for learning. When hands are outstanding in a dream it will usually indicate the dreamer's need to give attention to the intentions behind the actions."

I know that there is more to this.
