I never have slept well. I was a grown adult though, before I realized that other people's "sleep" was a totally different experience than what I had ever known! We had an elderly friend once (in his late 70's at the time), who was pretty upset one morning when he met up with us for breakfast. He had "woken up" during the night. I assumed he meant that afterwards he stayed awake and wasn't able to go back to sleep. But oh, no! He had immediately gone back to sleep, but apparently just being awake any what so ever was an unheard of experience for him and it had ruined his day! Never having known one single night of solid sleep in my life, you can just imagine how astounded I was by his being upset! 🤣
