Make me feel it even if it ain't true

I woke up from a dream of writing a chapter which began, "The first movie I ever saw by Derek Jarman was The Ascension." Which isn't true, first because that was Caravaggio (1986) and second because The Ascension doesn't exist, but I had an incredibly clear image of a still from the film: a blue sky running into a blue sea with heavy white clouds on the horizon so that the figure standing at the tide-line appeared to be set in the sky, wearing a bird-beaked mask and a broad hat with long, blue-black plumes and a kind of Renaissance-classical drapery around its hips. I couldn't tell if it was male or female or if it mattered. There were little hints of gilding all around its edges, but they were just from the slant of the sun. It was either an angel or a person who had become one. Because of Jarman, I want to say that the object between its hands was a mirror, but I honestly can't remember either way.
