Family Matters - Season 3 Episode 4 -

Urkel repeatedly sleepwalks into the Winslows' bedroom to belt Carl over the head with a newspaper. Harriette gets an annoyed Carl to call over a hypnotist to see what's behind Urkel's behavior ... and Harriette is more than a little disturbed by the findings. Turns out Carl had yelled at him after the nerd accidentally broke his ship-in-a-bottle, then - unaware that he was listening in - told Laura he wished he'd go away for good. Carl eventually realizes he needs to apologize.
