I think I have the most resonance and comfort in the thought that dreaming just is. There literally may not be a reason, or it’s simply impossible for the universe to exist without dreams. We’re in our bodies which can be seen and defined as separate from everything else so we try to rationalize and compartmentalize everything when the reality is both uniform/unbroken with distinct elements simultaneously. As beings of the construct, we are presented with choices, mostly binary ones, so we get lazy and complacent. Sometimes entirely missing out on noticing how caught up we get in making our choices that we forget sometimes there are alternatives to binary, or categorization. Dreaming lets go of the choices we’re exhausted from making and we get to tune into what the waking world is choosing. That sounds like a great truth to me.
