I'm just about sure I saw that either as a screne from an old game or some kind of robot toy face that was a decal or mechanically animated. Maybe I'm just going crazy. Wouldn't be the first thing I saw something in a dream and faintly remembered it as real.
I recently saw your avatar somewhere and I can't remember what it was on. Maybe an atari 2600 game? Help me out, it's driving me crazy.
