Mickey falls asleep after reading one of Lewis Carroll's books. An astral projection of himself leaves his body and wanders through his mirror into an alternate version of his house. His furniture and possessions have come to life complete with faces and personalities. Mickey eats a walnut and shrinks. He is now tiny and begins to dance his way through his house, dancing with his possessions and eventually the queen of hearts card. The joker, on his bicycle notices and alerts the king of hearts who fights for his lady and calls an army of cards after he is defeated. Chaos ensues and Mickey runs from the cards and blasts them with a fountain pen. He turns on an electric fan to blow the cards back, swings from a lamp rope, runs on a globe, and escapes to the right side of the mirror. Eventually he is awakened by his alarm clock and it has all been a dream, and goes back to sleep.
