Asylum (1972)

In order to secure a job at a mental institution, a young psychiatrist must interview four inmates in a mental asylum, and what what he hears is about 1) the revenge of a murdered wife, 2) a tailor who makes a suit with some highly unusual qualities, 3) a woman who questions her sanity when it appears that her brother is conspiring against her, and 4) a man who builds tiny toy robots with lifelike human heads.
