The sounds I've heard have varied greatly. The first time I did it I head a man say something in my ear, that scared me because it caught me off guard. I've also heard a group of children laughing one time. The crazies on was when I was just laying in bed relaxing and I was thinking of some weird log cabin. I pictured this women push a man down and I heard the 'thump' of him hitting the ground as clear as day. Crazy stuff
