My experiences in DMT land show me three sets of consciousness. Mine, the entities within, and the DMT experience itself.
The "entities" usually try to show me something or teach me something. Sometimes it's as simple as telling me not to worry about simple things like work. Another time, they poured out a bottle of negativity. Another, they had shown me how to freeze time but told me I wasn't ready yet.
I say DMT has it's own conscious because well, it seems to. It usually speaks to me about myself overall.
Like I used to be a giant dick. I was always mean, had a shitty life, and blamed everything on everyone else. DMT would bitch at me so much for being a horrible person.
After taking a break for a while and straightening myself out, and finding my true love <3, I got back into DMT again. In my first recent experience, it welcomed me back with warmth. DMT told me it approved of my significant other and that it was happy I finally decided to love. It then showed me my little girl, who was not even conceived of at the time. But, she's with us now!
For the longest time in my life, I wanted to denounce all things non-physical. Thing is, I've had a lot of weird experiences (while sober and confirmed by other people) that force me to realize there's more than us.
DMT well, I'm on the fence. In one sense, I believe it just amplifies our brain and lets us process things in a way we could never hope to.
At the same time I wonder if it's possible that DMT opens our mind in another way, to other places and other beings. I lean more towards this every day.
As for weird chanting or whatever, yup. I cannot remember for the life of me what though. It's not usually words but more like rhythmic humming.
