That's a scene featuring Montgomery Clift (along with Clark Gable, Eli Wallach, and Marilyn Monroe) from The Misfits, screenplay by Arthur Miller.
I had two really nice glasses of absinthe last night, I think I got the absinthe to sugar to water ratio just right, so maybe that explains the vivid, frightening dreams I had.
In the first, I was on a very flat world, a very flat orange sand island with a few dark, jagged brown hills under a greenish blue sky, and of course it was all surrounded by a dark, greenish sea. I was with a man and a woman and we were trying to escape from an infinite horde of zombies. The man and woman both got eaten pretty fast but I had some kind of jet ski I took out over the water. But the ocean was infinite and the zombies were swimming in the water, too, filling it completely.
In my second dream, I was told that due to some deficiencies recently discovered in my academic records, I was required to take nine high school classes every day for the rest of my life. I met some kind of sea goddess or demi-goddess played by Jean Marsh who took me to a small, shadowed lagoon on a remote island. She told me I could choose to take the classes or to be killed by her. I chose death and the last thing I saw before I woke up was her turning into a bear and attacking me. Well, let's hope I never have to make that choice.
