Dissolving Self-Created Limitations: Dreams and Emptiness

"If we want to understand how we are ordinarily misled by our false projections and how we can begin to break free from their influence, it is helpful to think of the analogy of our dream experiences. When we wake up in the morning, where all the people we were just dreaming about? Where did they come from? And where did they go? Are they real or not? Of course not. These dream people and their dream experiences all arose from our sleeping, dreaming mind; they were mere appearances to that mind. They were real only as long as we remained in the dream-state; to the waking mind of the next morning they are only insubstantial memory. While we were asleep they seemed so true, as if they were really out there, having a concrete existence quite apart from ourselves. But when we wake up we realize that they were only the projections of our dreaming mind. Despite how real they seemed, these people in fact lack even an atom of self-existence. Completely empty of any objective existence whatsoever, they were only the hallucination of our dream experience."
