Most of us would find it impossible to focus on anything with no lapse in attention for more than even sixty seconds before the internal dialogue begins to churn. I suggest meditation to learn how to quiet the constant rambling of the mind- give all of your attention to your breath in every moment. Should your mind wander, gently let it return to your breath. Over time, this strengthens one's capacity to maintain their attention on a single thing, or to remain aware and conscious moment-to-moment. As mimihigurashi mentioned, we sleepwalk through our days, and thus our nights. Awareness is the key to lucidity, and meditation is the key to awareness.
