One time out of the thousand bowls i smoked, the crackback of the meth had a bunch of spiral shapes in it. Some smaller some bigger maybe a dozen or two but most definitely uniformed perfect spirals (the closest resembling thing i could google was by describing them as illusion spirals, where the spirals go from big and to small from the outside to the center) Also the meth looked wet even when completly hardened. It was absolutely beautiful. I asked my friend if i was seeing things and she seriously saw them too and i have never experienced visual delusion before. We smoked it all before getting a picture. My phone had to of been dead or i would of snapped one but i figured the next bowl from the batch would look the same but it didn't. I have never since seen anything like it. I tried googling how this happened and this page was the closest i could find on such a phenomenon. My only reasoning at this point of how it was possible is God or Aliens because why would it be just the one bowl out of the entire bag and history of me smoking?
