The Flowers (1967)

Short animated cartoon about a lonely little fellow who walks down a road and keeps picking flowers, which out of the blue turn up in ever larger numbers. Driven by desires that grow in intensity as the bouquet expands, in the realm of dreams he meets three women who literally outgrow him. When finally, with a final effort, he picks the only flower left, the little lad collapses under the burden of his craving.
