Dreams are unconstrained remixes of reality. They manufacture light and float with fantasy, all lucid to the sleeper. Anxiety, happiness, emotions — it's all tangible in a slumber.
We dream when we're awake too — we just call it using the imagination. Yet, we restrain the material world to a predictable order. We crimp our creativity.
We make better movies when we dream to sleep. Being awake is a boring hallucination.
