There was a pond we walked past every day on the way into (Primary) School in a small suburban part of the UK. One day on the way in I kept my usual date with it by leaping onto the bottom bar of the fence to look at it when I noticed a hippopotamus head. As I watched, intrigued, the head rose up as did the heads of several others of varying sizes (some very cute baby ones too) and they started performing all sorts of tricks. It was brilliant
Because we'd stopped people were curious as to why and so started gathering around us. The crowd increased and traffic started piling up and stopped for miles in either direction. And this Hippopotamus circus was named after me as I had discovered them. Our family called the pond the Hippopotamus pond as I insisted on it.
15 years later in a moment of extreme sanity I realised this had been an extremely vivid dream but it was so real to me.
