How would you apply operant learning to finding solutions to a problem through dreams?

Operant learning/conditioning is the kind of learning generally based on reinforcement of desired behavior. (Reinforcement is any thing or event that increases the frequency or length of the desired behavior.) There would be many ways to approach increasing the number of dreams one has, and you can even train yourself to increase your experience of lucid dreams, dreams during which you become aware of the fact that you are dreaming. Adding the element of seeking solutions to various problems/issues would naturally follow.

But there are probably many methods of problem solving that would be easier and more effective than trying to solve them operantly with dreams. As it is, naturally occurring dreams can give us useful hints about what is going on and how we might deal with things creatively.
