The Hourglass Sanatorium (1973) on Netflix

Józef visits his dying father at a remote mental institution, where time itself doesn't seem to exist, and the line between dreams and memories becomes indistinguishable.

The film depicts its protagonist, Joseph (Jan Nowicki), traveling through a dream-like world, taking a dilapidated train to visit his dying father in a sanatorium. When he arrives at the hospital, he finds the entire facility is going to ruin and no one seems to be in charge, or even caring for the patients. Time appears to behave in unpredictable ways, reanimating the past in an elaborate artificial caprice.
