Between serving in 'nam and working a labor-intensive job with as much overtime as her could get, my dad could sleep anywhere. Sometimes so hard it took a phone or alarm to wake him up, and he’d be moving and talking before his brain even shifted into gear.
The secret is to accept some level of discomfort in whatever situation while attempting to secure a subconsciously safe-feeling location, and then your tired brain will do the rest of the work getting you to sleep.
I’ve fallen into a deep REM sleep right next to a diesel turbine once (wearing ear protection of course).
