At that dosage, I wasn't hallucinating but the part of my brain responsible for recognizing and making sense of faces and, in particular, facial expressions wasn't working anymore. For example, if my wife smiled, intellectually I knew it was a smile, but instinctually it gave the same feeling you get when you watch badly animated characters smiling or if someone were to make a surprisingly realistic face out of pineapple slices and ham or on a carved pumpkin. It just seemed wrong and made me intensely uncomfortable because I knew it should feel like a person, but instead it had that creepy uncanny valley feeling. Multiplied by 100. I'm finding it surprisingly hard to describe, I hope that conveys it somewhat.

With that in mind, now imagine the faces Nicholas Cage makes.
