From personal experience from sleep deprivation and from MOST of all my friends who all are clean and sober now from either cocaine or meth, all of them have a side effect till this day saying that they can hear everything and that it seems like everything sounds so loud just like when they were up for days. My question i've had for months is that why does sleep deprivation in a way, cause to you realize things that you dont sober? When i was up for 3 days, i felt like i could read peoples energies and minds, if it was someone who was rude usually their faces would look scary and change, but if someone was a sober person or just a nice person in general i could FEEL their aura and presence. Also, if someone was in the room next door, or even far from me its like i can sense them, also I COULD SEE MY OWN SKELETON IN THE MIRROR for like two seconds and than it changes back to normal. I could see little microscopic orgasnisms and molecules floating around and everything felt like the earth was spinning like it does in real life. I also saw BLOBS of brown stuff coming out my pores, that was dirt and impurity for meth i WAS NOT ABLE TO SEE THAT SOBER also, i could feel the nerves in my skin and it's so weird because from sleep deprivation i saw a lot of things that were their that i can't see sober. A lot of it were hallucinations but the shadow people, a lot of the small tiny bugs, were all real if you believe in ghosts that is but even if you don't, why does your sense of hearing actually becoming better in the sense everything sounds so loud, i thought it would of been the opposite. One time i was able to see through the wall and what i saw on the other side of the wall, was what really was already their CRAZY! Also i have been sober and away from all drugs except and occassional drink, and marijuana daily marijuana smoker. thanks sorry if it seems to cluttered and confused, i just had a real bad day, and am trying to leave this stupid library, so i can go back to my apartment and dwell.
