Lighthouse Man

Feeling like a lighthouse man means that you feel like you might be one of the villains from a Scooby-doo episode. They were always angry, yellow or green, disaffected, gangrenous looking and over all terrifying and ugly. Sometimes this was a big rubber mask, which is significant, because it indicates that you are not feeling like yourself. The actual lighthouse man has glowing eyes and terrible teeth. A corollary to saying you feel like a lighthouse man is to have others tell you to get back into your lighthouse, which means you look like a lighthouse man, and should go lie down before you commit a crime and the gang has to come and bust you.
