How so?
Please refer to my previous post, I already explained this
Doing hallucinogens can open your mind to seeing the innerworkings of your body. Literally. It reduces filters in your brain and makes you see things that you learned to ignore as a baby.
To me, doing drugs is akin to glitching out a computer program.
Cannabis impacts your memory, it's like periodically deleting your computer's RAM while it's running.
LSD and psilocybin is like circuit bending, literally creating new pathways between parts of your brain that weren't connected before. This is why it makes you see colors and fractals, you're getting junk data from other parts of your brain passed to your visual cortex.
Alcohol is like adding packet loss to your nerves. It interferes with signals from being sent and received between various parts of your mind and body, this is why it numbs you and slows you down. Much like in a computer system you have to constantly resend lost information, slowing down the total communication throughput.
Ketamine is like turning off entire subsystems. When you're in a k-hole you've basically turned off anything related to visual and motor processing. It can feel nice to reboot every once in a while.
Essentially, different drugs can either expand or shrink your experience of reality. Dissociatives and deliriants make you experience less. Psychedelics and stimulants make you experience more.
