One night, I dreamed of a man who was a walking dead. This man worked in my neighborhood. I was never close to him, but recognized him as a worker in the neighborhood. His flesh had decayed and emitted a putrid smell. He was trying to speak to me, to ask for help to save his life. He said he wanted someone to take his place in death.
This man in waking reality, suffered from a disease that gave symptoms of kidney and liver problems. He was an alcoholic who is now suffering liver damage. This explained the dream.
