Hey Nadia - you have one of my favorite names. Beautiful!
As you can see, I'm psychic - I posted the answer to your question at the same time you were posting it. ;)
I think what happened was that that situation with my friends' child triggered the dream, and it somehow incorporated several themes that I'm obsessed with into the same story idea: the deal with the devil, and the question of what we really are willing to do for those we love (we always say - "I'd do anything" - but what does that really mean? And is it really a good idea to be willing to do ANYTHING?
I'm very glad you're responding to the premise. And I hope the hospital lives up to expectation - the real one in Boston is certainly one of the spookiest places I've ever been!
