‘ When you see faces in random objects, think “human imagination” not “aliens”. ‘

Yes, and even light marijuana use greatly accentuates that. Faces, birds, etc., everywhere. The pattern-recognition circuits of the brain go crazy, with enhanced functional connectivity, and the images grow more distinct as you concentrate on them. Even MJ users know these are not real, however.

No matter how I looked, I could not agree and I'm reasonably good at seeing patterns.
I guess I was too sober.
