Sometimes your mind wakes up and your body can't move. It's a special form of paralysis usually signifying a visitation by a demon or even a gargoyle. Daly didn't believe in such things, not unless they had a material naturalistic explanation. As he lay there though, deposed of the ability to move his limbs he couldn't help but feel that something else was present. The presence didn't seem to be outside of him, it was somehow inexplicably inside.
