The best night's sleep I ever had was on the sand of a turn in a dry creek bed, after a very long day's hike. It must have had a big rock underneath that caught the day's warmth and kept me toasty all night. And the sand itself felt like floating on a cloud. It was a magical place. And one of the stupidest I ever slept in due to the risk of flash floods.
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 was reading your first sentence with apprehension as my first thought was flash floods!
Glad you made it out safe, with a story to boot.
One of the best meals I ever ate was a store bought can of chiii cooked over a tiny camp burner after a long hiking through the Grand Canyon. Sometimes it's the simple things during the most exceptional situations that can cement such a strong memory... It did for me anyways.
