Yeah. In addition to the two nightmares the kids spawn, I am certain there are x minutes on each of the campfire's levels for the rate, with 'x' becoming a smaller number with each upgrade, therefore shortening the time between each nightmare spawning.

So they spawn over time too, more often if the campfire is of a high level.
