I was not aware of the entity thing prior to trying DMT. I was not aware of people like Terence McKenna yet.. I’d read a few experiences on erowid but from memory a lot of those old trip reports I came across didn’t really talk of entities. I was just expecting a really really strong version of LSD.
And even going into experiences like LSD I had a completely different preconception of what that experience was going to be. I just expected colours and tracers, sound enhancement and electric eye candy. To then have Mayan/aztec-like patterns dripping down the walls with strange hieroglyph like characters was mindblowing for me. Tribal style patterns made of energy organizing themselves on my best friends face.. while his teeth glistened with diamonds as the light refracted off of them.
The explanation of the visions just being a manifestation of noise in my sub conscious falls short for me. There are many things floating in my sub conscious, such as the multitude of mundane things we deal with in day to day life. Why is media I consume, or the various chores I do on a daily basis not sown into the visions? The animals I see, the shops I go into, the car I drive.. all this stuff is generally omitted from the psychedelic experience and it always has a far more mystical quality.
I was an atheist growing up, with no interest at all in spiritual tradition, so this was quite a shock for me.
Why religious iconography suddenly becomes prevalent in these experiences is not well explained. But I can say for myself that the intelligence/entities in the DMT experience came as a surprise and I haven’t really found the reductionist explanation for them particularly compelling.
