"I began to laugh uncontrollably, so hard I nearly fell off the swing, because I knew then for sure he saw the same thing I did. More than that: we were creating it. Whatever the drug was making us see, we were constructing it together. And, with that realization, the virtual-reality simulator flipped into color. It happened for both of us at the same time, pop! We looked at each other and just laughed; everything was hysterically funny, even the playground slide was smiling at us, and at some point, deep in the night, when we were swinging on the jungle gymand showers of sparks were flying out of our mouths, I had the epiphany that laughter was light, and light was laughter, and that this was the secret of the universe. For hours, we watched the clouds rearranging themselves into intelligent patterns; rolled in the dirt, believing it was seaweed; lay on our backs and sang "Dear Prudence" to the welcoming and appreciative stars. It was a fantastic night: one of the great nights of my life."
