How about this twist of thought on the subject?

When you think about him in waking life consciously you lay out your desires and thoughts and whatnot of him to your hearths content and then don't have to dream about it as you went through it in waking life but when you then don't go through that which you want by thinking of him in ways you want your subconscious reveals those things to play out in their way you want in your dreams instead.
IE you don't need to ravel through things that are clear to you twice both in waking and dream. If one is gone through it in either it's settled and other things maybe are more important to be assorted in mind?
