I understood the meaning of alpha hallucinations. It's simple. God, for whatever reason, could not prescribe when he created life that man had an unbearable fear (no reason, no trigger) - maybe he tried to do so, but it was either too soft/hard, or low-efficiency, or lethal, in general there was some treble with it. Therefore, in order for a person to beat fears and other negative emotions, he built a cunning scheme that a person always has a process in the brain of assuming a potential threat of threats formed in the depths of the psyche into creatures invisible to the eye that are going to attack you. In the brain it was laid by the creator himself to generate them so that a person experienced fears. When you take alpha, this process becomes visible to the human eye. Since this is a brain process, it is able to both create new characters by drawing energy from the resources of the imagination, and compose them with speeches, give them manners of behavior and provide these creatures with knowledge of your weaknesses and phobias (because the brain itself stores this information), all this causes a surreal picture of some demonic dimension torturing you to suppress.
