You should try sleeping on a fresh haystack. Most people will never experience this. But the haystack is made up of cut flowering meadow plants. So it's like sleeping in a bouquet of dried flowers. And the aromatic organic chemicals released all night can have a very calming effect.
It's kind of wild to think about, but people used to get it on in haystack barns all the time.
I tried that and it was made of cut grasses. You know how grasses have foxtails that cling to animals to help distribute the seeds over a wider area? I was that animal that night and I didn't like it one bit.
