To me, it is like having the shit scared out by a near-death experience (that ice-through-your-veins panic feeling) followed wrapping yourself in a blanket made of joy. Eyesight is not applicable, go ahead and try to explain what you experience, you can't. I never felt 'alone' like I did w/ LSD and shrooms. I took things way too far though, can't touch any of it anymore. 2 years it took to accept the new normal from the last mushroom overdose.
