A person close to me recently stayed in the room of someone who had died not long ago, someone she'd known for years. Out of respect she lit incense and retorically asked the deceased for permission to stay in his room. A few hours later she went to sleep. As she was entering into that half wake half sleep state she felt a comforting hand on her shoulder. She asked herself if she just felt a hand on her shouldner and realized that yes she had for sure. Then she went to sleep feeling most welcome.
