First off....what the fuck...the phrase I've been repeating for the past 20 minutes...
I was in the exact same place as you in late 2010.
I had plenty of tripping experience but I had never truly had an ego death experience. When I came back I said "what the fuck?" and "that is impossible" for like an hour. I couldn't sleep that night, I was up all night thinking about it. That trip completely shattered my worldview.
I know exactly where you are coming from. It took me a while to integrate that one and I didn't smoke again for a few months.
DMT is some crazy shit, isn't it?
Honestly, i don't see why people bother with pure crystallized DMT, i myself much prefer full spectrum.
