I served on a submarine. We were so isolated in our own reality that we practically had our own language by the time you waded through all the idioms that were shorthanded out of common experience.
No one wanted to be 'cupped,' referring to an incident involving an unpopular crew member's bunk and hundreds of paper cups stapled together and filled with old lube oil. To people outside the crew "watch out man, you're looking to get cupped" made no sense at all, but it was our equivalent for "check yourself." "Might get bagged" was someone who probably wouldn't get into trouble on their own, but would go along with a bad plan, and referred back to the time honored tradition of giving a seasick guy who was stuck on watch a clear plastic bag to puke in...to see who else would get dragged into puking even if they weren't particularly seasick to start with. Examples by the hundreds.
So I suspect that everyone has some sort of bubbled existence, but without any genuine forces of isolation the effect is probably limited. At least compared to a submarine crew.
