When I was little I had a nightmare about crocodiles being on the floor of my bedroom. After that, every time I woke up from a nightmare I would be convinced that the crocodiles would be back as well (it didn't matter what the dream had been about) and I would sit in my bed being very scared to reach out and turn on the light, because I thought a crocodile would bite my arm off if I moved it off the bed. However, I knew that if I managed to turn the light on, this would make the crocodiles go away again.
I think this might have had something to do with having just moved house, with a green carpet in my new bedroom.
