Alright, that might sound bizarre, but that is a classic example of free association thanks to today’s daily prompt.
So first things which to my mind when I hear (okay here read):
home: sleep, laze around, computer, mother (yeah really!) and scratching wherever I want freely :P (quite true isn’t it?)
soil: mud (pardon my lack of imagination at times)
rain: smell of mud, walking, hiking
And as the title says, I did sleep on the mud in the countryside and mountains quite a few times. You should try it, away from our monotonous lives, really bliss.
