Just my thoughts on practices such as Evocation, various methods of projection, and other practices involving seeing and hearing spirits generally. Such experiences from occultists tend to be very contradictory from others at times, and usually others may say the spirit that appeared is a parasite/imposter, or that the information received is symbolic. That could definitely be true but it’s also worth asking whether such practices are always reliable in themselves. For some people going through such experiences, especially if they are very negative, when you look at the experience and thought pattern in a sense, you will see the same or very similar experiences outside of Religion and the Occult, particularly from conspiracy theorists (especially), and people with certain various forms of anxiety disorders as an example.
With drug use, similar experiences can be had that are not definitely not reliable, mostly because drugs purposefully affect certain functions of the brain, and the brain is very capable of emulating such experiences, even outside of drug use (Some people essentially train their brains to constantly have the affect of hallucinogenics but without experiencing effects that other parts of the brain govern, such as paranoia). Of course, evocation and other experiences can feel extremely real, even more real than what you experience going through day-to-day life since you tend to be more aware, but various mundane experiences can feel the same, such as the drug use and tricking the brain into thinking an event is happening. I think many who deal with anxiety and OCD can say how real a false health crisis can feel at times as well, and how the brain can trick you into some very weird realistic feeling sensory experiences. The brain is fully capable of producing all kinds of experiences since our entire experience of reality is experiences through the brain, and our experience would not at all be the same without the brain’s structure since consciousness itself as actually on a very base level. Closing your eyes and imagining a landscape and walking through it can also begin to feel extremely real if you let everything become automatic, but the tiniest amount of power uses at the very back of your mind can direct the entire experience. The brain can do a lot even though it feels like you’re not the one controlling the experience.
Of course, I’m not trying to say anyone’s experience is “false” and no doubt much of it is real, and all these practices can be reliable without a doubt, but I think it can be worth it to bring up such questions, and just observing and analyzing one’s experiences. I’ve had quite a few times where my anxiety made me feel like an astral parasite was attacking me when there was nothing and nothing came of the situation, as well as plenty of other occult experiences that were probably false. So it can be good to just keep an open mind about things, and of course do test the practices.
