Ciro-Norte (1998)

On stormy night in an ugly urban landscape, Ciro Norte, a scientist with wild hair and thick glasses, straps himself to a chair he's has fashioned with wires: lightening strikes, convulsing him. It seems his experiment has not worked. The next day, he drives his jalopy to a bar, sits alone, and weeps. But suddenly, a vortex sucks him into a dream state where he wanders, escapes man-eating fish, confronts his doppelganger, walks through a field of giant flowers, and comes upon Venus herself, buried up to her shoulders in sand. She is a giant, and she takes him to her breast. He wakes from the vortex, back in the bar, his mood transformed.

Unfortunately the movie Ciro-Norte is not yet available on HBO Max.
