Late-Night Listening

I put my HA's in late last night (or, extremely early this morning haha), whilst my window was open, and closed my eyes for a few minutes at times, to just breathe and listen and feel comfortable. I could hear the wooshes of cars zipping down the road, trucks in their rumbling graveyard commutes, and when things calmed, the sound of...the night air--you know, that subtle extra bit of 'white-noise'-type sound that floats into your HA's and settles there?! And who knew that rustling sheets/blankets could sound so crinkly and noisy at night?? Do they sound like that to 'normal hearing' people?? I feel like I have to be a mouse sometimes, when wearing them!
