During a discussion about staring into space on Airedale-L, Terry in Seattle recalled the way one of her 'dales would stand by the bed and stare if he had to go out during the night. She wrote, "Did you know that it is possible to awaken an adult human at 2:00AM in a pitch dark room simply by staring at him? How DO they do it?"
I remember The So-Perfect Darwin doing the same thing. I'd float up from sleep, open my eyes, and there he'd be, staring intently from a few feet away, too far for the touch or smell of dog breath to have awakened me. It had to be the thought waves.
