At the risk of being "that other guy", psychedelic experiences come in many different categories of experience: ranging from mere distortions of our normal, subjective state of perceiving reality, to emotional processing, ego death, out of body and spiritual experiences. There is no formula for a spiritual experience, but there have been enough accounts of mystical experiences throughout human history that point to them being quite literally "spiritual" - ephemeral, outside of or interacting with this three dimensional space we inhabit in ways difficult to comprehend, a true mystery to this physical instrument through which we filter the universe.

I think it's a mistake to think we have it all figured out just because we've had an experience that either reinforces or contradicts our per-conceived notions of what constitutes reality.
