My Wapped Dreamscape

This occured when I was 4, staying in France with my grandparents. The only bit I remember went as follows:

I was outside somewhere with a few friends.I had a water hose to my mouth and was drinking the water when suddenly a live fish comes out and before I knew it I had swallowed it. I could feel it in my throat as I woke up screeming.

Explaining this to my grandperents who couldn't speek English was difficult, the nearest I was able to come was "Pictures in my head when I sleep" it was then that I learned the word cauchemar and was told by my grandmother that it was because that night had been a black moon night.
