A childhood belief about under my bed

I didn't have any fears of things hiding under the bed, until my next door neighbour (a few years older than me) told me that she had things called 'Mutton Jeffs' hiding under her bed, that would 'get you' if you even stepped on the floor, even in daytime. Whenever I went over to play at her house we had to jump from her bedroom doorway onto the bed, and stay there - using the furniture to climb around the room. She even showed me a mutilated doll - that she said the Mutton Jeffs had eaten. Then one day she said they had come to my house - they were under my bed, and my parents bed. I remember dreaming about them - they were invisible but had vivid green eyes that glowed in the dark, and I remember them chewing at my fingers, but thy were all numb, so it didn't hurt much (I guess I had slept on my arm and it had 'gone to sleep', so I was actually getting pins and needles), but ever since then I used to have recurring dreams about what they were doing, and found out that they couldn't get me if I sat on the magic carpet (a big rug in my parents room) which would rise into the air if they tried to get near me. Luckily, we moved house, so they couldn't come after me any more.
