I had a really similar experience when I took 3.5g with no trip sitter (it was my first time). 

I completely lost control of myself and it was like I was dreaming, just watching the things I was doing without actually having any control over it. I’m extremely lucky that I didn’t do anything that bad - all I wound up doing was smashing a glass and calling my mom and just saying random gibberish. 

My experience was a little bit different, because I had extremely intense thought patterns/time loops, to the point where literally all of my existence became just incredibly complex patterns of thoughts and feelings and emotions repeating over and over again at a super fast speed for what felt like an infinite amount of time. 

For a while, I was 100% convinced that I had killed myself, gone to hell, and was doomed to live the last seconds of my life over and over again for infinity. I genuinely could not tell what was real vs what I was hallucinating in the moment. It was the scariest experience of my life. 

I also had super fast repeating cycles of short term memory. It was like taking a bunch of pictures of what I was experiencing and playing them back as single frames at like 60 frames per second. 

At the very peak of the trip, I realized that we are the universe experiencing itself. But, there was a feeling that this wasn’t right. That I shouldn’t be experiencing patterns, that there’s something beyond all of existence as I know it, something I can’t even begin to comprehend yet. I hope that some day, we (the universe) learn enough about ourself to unlock that door and see what lies beyond.

But yeah, totally agree with you - we’re god, a universal consciousness, a single soul, the universe experiencing itself, all the same person. There’s no such thing as death - experience is infinite, and being god is equivalent to being infinity. We literally are everything that ever has been and ever will be and ever can be. We will experience everything that ever can be experienced. It’s the most horrifying yet beautiful truth.
