DMT sounds wild, everyone reports about interacting with a great serpent that is very stern.
i don't want to fill this topic with off topic information so ill keep it short:
the entities you see wile taking part in something like DMT, the way how people describe how different they are and how out of this world they seem take these types of descriptions as compliments of the highest regard.
right now we are playing the make pretend game of mono-dimensional. what you see wile taking part in DMT is your omni-dimensional self, you see the clear picture with all the blinders taken off.
because we ordinarily go around everyday clinging to the blinders (like an anchor) for an illusory sense of temporary comfort through ignorance it gives us the distinct impression the entities we see on the other side are decidedly "alien" or different than what we identify ourselves to be.
the comfort that is derived from ignorance will drag you farther into the matrix and make you progressively less sentient.
the discomfort derived from learning the hard lessons and learning things you felt like you did not want to know will push you further out of the matrix and make you progressively more sentient.
its important to understand sentience is not a singular point and non-sentience is not a singular point either they are directions of exploration that are both limitless.
