Juliet of the Spirits 1965

Middle-aged Giulietta grows suspicious of her husband, Giorgio, when his behavior grows increasingly questionable. One night when Giorgio initiates a seance amongst his friends, Giulietta gets in touch with spirits and learns more about herself and her painful past. Slightly skeptical, but intrigued, she visits a mystic who gives her more information -- and nudges her toward the realization that her husband is indeed a philanderer.
