At night I locked my bedroom door, because [my father] could not sleep and would insist on talking to me, endlessly, without making sense. But there was a small window over the door which could not be locked. One night I woke up to see him slithering through the tiny aperture and jumping nimbly to the floor. But he paid no attention to me. He aimlessly picked up various pieces of heavy mahogany furniture and let them drop with seemingly little effort. In his insanity he had become superhumanly agile and powerful. Staying with him was a nightmare.
