a one day project

I was in a valley with mountains surrounding it.
And there were also some hills that were near, that had a kind of a flat side kind of a slide.
Someone asked me what was the project and I said that the idea was to roll down from one of those hills, and it didn’t matter if it was from not so high or from the top of the hill.
People started to roll from different heights and I started to record how they rolled.

I didn’t named it in my sleep.
