You study your own vibrations for a long time
Looking out through the eye of your pineal stalk, it seems this space you are in cannot be real, everything shifting and distorting in simple oscillations and collapsing patterns of colours, wavy lines, and wobbling triangles... but what about the tactile sensations? Those are real.
Gently, you trace your fingers across your forehead, slowly moving them toward the hole, fearful of accidentally poking your eye-stalk or causing it to retract suddenly. You wave your fingers in front of it, hoping to see some change in vision linked to your movements, something to confirm your vision is of the surrounding environment and not just all in your head. What you see startles you.
More than just seeing your waving fingers, you actually narrow your sight and zoom in on each individual finger, and see through it, and through the strange foreign matter covering you, and see through all of it. This vision is not distorted at all! Everything in your reality has always been these simple, repeating patterns! It is only now, with your false eyes shutted, and your true eye open, that you perceive things as they are!
