" I don't--know about ghosts, but I do know that our souls can be made to go outside our bodies when we are alive... A very easy way to feel 'em go is to lie on the grass at night, and look straight up at some big bright star; and by fixing your mind upon it you will soon find that you are hundreds and hundreds o' miles away from your body, which you don't seem to want at all. "

― Thomas Hardy , Tess of the D'Urbervilles
