I had several profound "I am God" experiences a few years back. As did many of my friends who also partook the spice at the time. I've also seen this mentioned by probably a dozen or so people on the internet now, maybe even more. These facts alone make it pretty intriguing -- people all over the place having, in many cases, experiences which are descriptively identical.
The first time this happened to me occured after my third spice trip, and the first spice trip by myself. It was a billion times more intense than any other DMT trip I ever had. I was so stunned upon returning that I went into a shock-like state, flailing about in my yard and howling uncontrollably in a pleasure so intense I thought it was going to kill me, or already had. The details of that trip can be found in a report I wrote about this and posted it here awhile ago, you can dig it up if interested...I don't care to repeat the whole thing. But it was my first complete dissolution into eternal infinity, though I had no idea what to make of it afterwards.
I also had quite an experience tripping on 10g Cubensis and insnuffulating +/- 300mg DMT at the peak. I died and became one with God, forever. It wasn't like I went someplace new; I was back to that familiar existence w/o form which I had merely forgotten about or something. I also believe I posted this trip report here as well, obviously there's a lot more details.
This went on and on and I eventually came to believe that the DMT state was the real reality and that it was somehow possible to transcend this world and to become a real God...and that this was possible for everyone. Thus my life took a new direction, which ended up with me getting in a lot of trouble for DMT and other psychedelics. I was a "cult leader" and used psychedelics to "brainwash", according to some sources.
Anyway, it's a long fascinating story, and today I don't pay any of that much mind. No matter how much DMT you take, you're always going to come back to this world. Whether or not the DMT world is real or true remains to be seen. It seems real, being as vivid as it is, but I take the spice with a shake of salt anymore...though it's true that I hardly ever use it, and haven't found it to be very pleasant or deep in years. I found that I had wanted to believe in the DMT world more than I was willing to approach it from a reasonable point of view. For all practical purposes, whether or not the DMT world is real or not doesn't matter. We live on Earth, not in hyperspace, and it's really a waste of energy to get your head too wrapped up in it.
