Requiem for a dream?

Sadly to say so, but I have not been dreaming recently. I have been pondering this idea for a while and I think the more you think while you are awake, the less you dream in your sleep. My idea is that everyone has a conscious in the awake reality, now if everybody uses their ideas and strategy's all day there must be a halting point to everyone's opinions, after all everybody's dream is definitely their own opinions. If the thought process is going on all day long  then the dream reality is deeply diminished for the fact that the mind is exhausted throughout the long haul of bodily functions and thinking all day. Thoughts?
