So when I used to close my eyes before LSD i would just feel normal, I could feel my brain working when it took in information. Now its feels like when I close my eyes, nothing is there, It no longer feel my brain, it just feels like empty space. Now when thoughts arise they don't feel like processes in the brain, they just feel like clouds floating through air. Lsd completely unprogrammed the mind and reprogrammed it to work exceptionally natural, the mind feels elastic, able to take in information in one whole spectrum instead of piece by piece. Although i noticed the effects before i recently noticed how increasingly empty my mind feels, i can't even feel my mind enough to have a headache. Comments on this phenomenon.
some people notice an increase of noise from their cranial machinery post-psychedelics, its all very personal, whatever that means.
Practice using your third eye. Just remember that all eyes need rest. If you don't like the empty, fill it with something. Daydream if you please. Personally, I almost like the emptyness. It's clarity to me; I am free to observe the environment around me, manufacture thoughts as I please, and drift with whatever thoughts come to me.
