"I first encountered this phenomenon in the early 80's, but it seems They have existed since the dawn of the human race.

As long as you don't know you are dreaming, you are safe... They attack when they sense a mind detached from its body, which sometimes happens during comas, but much more often during OOBEs and Lucid Dreamin."
