I mean like performing a Goetic evocation with light entheogenic enhancement?

Do you even really know what people are talking about when they say “spirits”?

Silly people.
Sun, basically I mean putting your self in a semi-dissociative trance state and conjuring up the denizens of your deep psyche into a more or less visible, and definitely felt, form whilst (temporarily) tricking your brain into believing that it actually exists as an independent entity outside of yourself for the purpose of communication.

If a person claims to have made the attempt to summon a spirit, yet hasn’t even attained such a mild breakthrough past certain psychological barriers, then that person wasn’t competent enough to be successful in the evocation to begin with.
Oops! I mean wolveswind for that last detail, not gay sun.
