Answer:
There was a story I used to read where a woman had her hands and feet dangling off the bed while she was asleep in her bedroom with her door shut. She woke up in the middle of the night to her dog licking her hand and dozed back off. She then woke up in the morning to find her dog scratching on her door trying to be let in. The dog wasn't in her room all night, he was shut out. This scared me as a kid because that meant something else was under her bed licking her hand. This influenced me to keep all my limbs on my bed at all times, and sometimes I would even keep them all tucked away under my blankets to be extra safe.
