An observation about visual processing. dancing ballerina / spinning dancer optical illusion made easy.
A personal anecdote.
One evening, I remember walking up St. Martin's Lane on my way home from work. I had a moment where my brain failed to understand what I was looking at. I saw a person with no face. The eyes nose and mouth were missing, the face was blank flesh. It was just for a moment, then the eyes, nose and mouth appeared.
I suspect this illusion happened due to tiredness and the level of light.
