Sleepthink
Thanks, dawgit, I'll pass that on.
Yes, I think the way it works is based on the very reason we have dreams. In our waking, rational mode we often limit our view of a problem to what we think is germane, which sometimes masks a possible solution. When we sleep, those seemingly logical boundaries are removed, we associate more randomly, and we come up with connections we never dreamed of (har) while awake.
