That's not how sleep works at all. Your sleep goes through many different phases and your brain is continually monitoring its surroundings for danger[0]. The reason why you feel like your mind is shut down is because, on a normal night of sleeping in your comfy home, nothing extraordinary happens. Try sleeping in the wild, it will be a whole different experience.

The wild is a very different environment from a train ridden by a dude with years of acclimation to it.

A comfortable train seat or train bed is definitely a place where a tired person can and will ass out. I’ve slept through a plane takeoff and food service and thought 5 minutes passed, only to realize it’d been hours.

When my son was eleven, I took him on a flight from NYC to JNB. He passed out after the dinner service, somewhere near Bermuda. He then complained to me that he couldn't get to sleep... as we were just crossing the coast of Angola. He absolutely refused to believe me that he'd been asleep for about ten hours.

I managed to sleep and snore while watching some music videos on my phone in bed. I could swear that I didn't sleep, but my gf had other opinion. It's also common for me to do midday nap and still hear everything that goes around me.
