The Ballet Master's Dream(1903)

It's late in the evening, and the ballet master's bed has been prepared for him. But he cannot take his mind off of his work, and instead of going to sleep he paces the floor and tries out dance steps. Finally, he goes to bed and falls asleep, but ballet dominates even his dreams. He sees two dancers who seem to come right into his room as they perform, and that's just the beginning.
