lol after clicking the permalink to your comment i was quite confused where i ended up and how this was related as i already had the gist about what this is about, but i totally threw me off XD

yeah, i too think its water related.i tried, water, rain, cloud, clouds, storm, vapour, steam, ice, ... cant remember more, also wind for the heck of it.

ok, here another hint:
its something that can happen with a river.
it is often used as a trope in movies or series (often comedy) that take place in the wilderness/forests

i was way past that as well, but it somehow just clicked at one point
