Good Evening (1965)

Daisuke Hamamura (Hiroshi Inuzuka), a driving instructor, is rather unremarkable and doesn't attract the attention of the women around him; the only one who shows interest is the landlord, Rie (Chieko Murata). One day, Daisuke finds a puppy and names it "Chibi." When he sleeps with Chibi in his arms, he inexplicably begins to dream of beautiful women, and soon he has pleasant dreams of beautiful women every night. Then, one day, Chibi runs away, and Daisuke takes time off work to search for him, but he can't find him anywhere.
