DUUDEE me too, when i get super faded everything looks exactly how u described it a 2d background, and anything that does move which is usually my friends because im focused on them is in front of that background. Basically like there is 2 visual layers that i can see, this is when there is a high chance that i will have high levels of anxiety or if i don't control my mind i will go into a panic attack. It really sux balls but to tell u the truth these are the times where u get the highest on weed. And to the ppl who don't experience anxiety or havent had a panic attack on weed, they dont know jack shit of what the true powers of weed are. If ppl tell u that u can never get too high on weed, just know that u have definitely been higher than they have : p
