I used to get those as well as a kid. The technique, nightmare-within-nightmare was a trope of 80s horror movies and that's where we got it (incepted?) I believe :)

On the movie, I think the really interesting part was not the recursive dreaming but rather how our ideas- that we think are novel - are not actually ours. After watching it, me and my wife started observing it on each other. Me or she would come up with something and the other would point out some conversation in the recent past that seeded it. Fun and a bit scary.

True. In the creative writing world, there is this notion that we are all pulling the ideas from our stories in some alternate space where ideas freely flow.

And when we notice how our original idea (and we're sure it's the first) is too similar to another who beat us to publication, yet both parties are sure no one copied anyone... well, it gives credence to the idea that there is an alternate space out there... or maybe we can access each other's ideas on some quantum level.

Speaking of quantum level, it might even be possible altogether.
