I woke during the night when my son was about 3, and heard him whimpering, like he was talking to someone. I went into his room and he was sitting upright in his bed, staring at the doorway, where I was standing. I went to him, saying his name, but he never answered and his stare never wavered from the doorway. By this time I was really worrying, so I started shouting his name, hoping to snap him out of it. All of a sudden, he said 'what,' still not looking anywhere else but the doorway. I asked, 'Who are you looking at?' He turned to look at me and said, 'The man in the doorway.' Then he laid back down and was fast asleep.
