It's like a metaphor for our whole relationship.

It's kinda fine if you position the arm below their neck so it's not crushed as much.

Arms don’t fall asleep in Eden

I got a few scares after falling asleep with an arm over my head, not even crushed, just up. It probably pinches a nerve or something. When I'd wake up it's like my arm was a dead weight for a minute, I'd literally have to grab it with the other hand to reposition it.
