Hey man.

1st off.  Seems like you smoked some especially potent synthetic cannabinoids.  There is a thread here on the Nexus where I speculate on whether the commercial SPICE brands have co-opted our term for the Divine Moments Of Truth.  You are not the first person to confuse the two.

That said, cannabis and the synthetic cannabis products can be quite trippy and result in spiritual hallucinations.

2ndly.  You seem like a very thoughtful and straightforward guy.  Your ideas are interesting, and your experience doesn't make you crazy.  Messiah Complexes are very common.  Common enough to be a well known complex , heheeh.  These things are usually temporary, but there is validity in the belief that every person is a potential Christ, Buddha or messianic figure.  At the very least, we are not really seperate from each other, and in moments of expanded consciousness, we often feel this connection in very visceral ways.

Be well my friend.  It is not an accident that you stumbled into the Nexus.  There are no accidents.
