that sounds like it just went overboard. actually it reminds me of the time i had a panic attack.
also, "awareness" maybe isn't the best word, since arguably one is less aware on drugs since the brain isn't working right anymore, which is what all these "fun effects" come from. but i couldn't think of a better word. i kind of think it messes with the perception/tracking of time/moments as well as inhibiting something that would keep you from becoming utterly engrossed. so you're stuck getting engrossed in everything, which could well lead to panic. but it *feels* like being more aware in the sense that you can watch things your mind is doing all the time, only now in slow motion, assuming you don't end up falling into an anxiety attack. so if you're deep in your thoughts, it feels like you can go even deeper.
i don't know what causes the anxiety when that happens... part of it can be that even when not high i've noticed how my thoughts can ramp up anxiety. i've had panic attacks before, and generally they were caused by my own thoughts. in response to every thought, is an emotion; emotions create more thoughts which create more emotions, etc. but i wonder if sometimes these panic attacks with weed can happen because the dose is too high or something. and maybe the initial panic arises because somewhere you know something is wrong.
after my total panic attack on it, i realized my thoughts were ramping it up, and that was how i realized that whatever my perception is, builds. so i try to not allow anxious thinking when high. if it starts up, i'll change my thoughts to something that isn't creating fear. it's just not always easy since sometimes reality doesn't feel right when high. like one time i felt like my head was in a box and it was pitch black on either side of it and i couldn't move my head. when something like that happens i find a thought tangent, and start going with it, because eventually whatever awful thing that is being experienced will stop thanks to my new focus. this keeps it from building into something worse, e.g. what if there are lions or snakes in the dark?
but the point is that what is enhanced is what you're already doing. so my experiences on it aren't abnormal for me, but what my mind often is doing, only now in slow motion. nothing has changed really other than that time isn't passing right. this was what i noticed the first time i got high, when i didn't know what to expect, or even that i was high. i was watching the credits to a movie, and i noticed that they were traveling in time loops. shortly after, i realized that it wasn't the credits but that something was wrong with time. for some reason i'd mometarily forgotten about how weed scrambles logic and thinking until reading your last post - maybe that's why time might seem to be going in loops.
i suppose one question about weed, which comes up eventually with any drug, is ultimately what is it really good for? i suppose i feel like i notice things in my perception and thoughts or things about others that i wouldn't have otherwise noticed. but it's equally possibe that every thought when you're high feels like a staggering revelation when it really isn't, and you would have thought that anyway (and more coherently) if sober.
i remember an article about pot heads reporting they felt *so much more aware aware and in touch with the universe!* but more objective tests revealed that they became less aware the longer they were on weed. lol. which again fits with my theory. feeling revelatory? well, weed will really allow you to build on that feeling. give it an hour and you will feel like the most brilliant person who's ever lived.
also from watching the show 'weeds' i remember that our um glorious anti-heroine would talk about "full-body highs" sometimes, which didn't make much sense to me at the time, until that first time that the sensations randomly were ramped up... then i realized *that* was what she'd been referring to. and that was how i realized there's a 'choose your own adventure' component to this.
in short though, it's not like it's new or different, it's just your reality *is* your perception... and weed is enhancing what you already perceive. but your perception is multi-faceted, and weed can allow you to pull one thread of it out and become hyper-focused on it (there's an unraveling effect). whatever benefit that may provide (if any), i don't know. but while high, if it feels beneficial, then of course you'll start thinking more about how it is, become engrossed in that, and be utterly convinced.
(or i will...)
