Sleepy Time Donald is a Donald Duck short released 9 May 1947.
Donald Duck is suffering from sleepwalking. He makes a nightly somnambulatory stop at Daisy's, as if he were showing up for a date. Knowing that one should not wake a sleepwalker, she plays along, but finds it difficult to keep Donald from being injured when he innocently walks in dangerous places, such as the lion's cage in the zoo, up a wall, and even upside down. When she finally gets him safely back in bed, he wakes up, sees her sneaking out, and thinks she's the sleepwalker.
