Unclean spirits are a topic that has been studied by me recently in my search for truth. It was a subject covered in scriptural account of the ministry of Jesus Christ. There was another night vision I had of the spirit of a great medicine man. He visited me in this vision and I clearly saw his face and was introduced to him as if we were communicating face to face. It was in fact during a time that I was not awake and conscious.  Upon waking the great thing about this time in the world is the ability to read and view reenactments of the history of his life. His life was one focused on death in so much that he developed a dance for the living to celebrate the spirits who are free of their temples of the flesh.  The dance is still practiced by many to this day.  A dance of ghosts.
