Sometimes your dreams get mixed up with your reality and you're not altogether sure where one ends and the other begins.
You understand what's going on, but are helpless to the outcome. Intrinsically tied to the fate prescribed to you by your subconscience.
But then there are those times where you can interfere. Something doesn't seem quite right, your conscience, the older and wiser brother, steps in and sets the subconscience straight.
And so you wake. Aware that because you now have control over the dream, it is no longer a product of your deeper soul, and so has lost its meaning and purpose.
