Forbidden Dreams (1982)

Paolo Coniglio is a naive and clumsy employee in a comics publishing house, bullied by his manager and his terrible future mother-in-law. To escape his dreary daily routine, he finds himself living vivid daydreams with "Dalia", the beautiful heroine of the books that he's translating. One day, though, while shopping, Paolo meets a charming blonde that looks like Dalia, and finds himself trapped in a shady intrigue.
