Ascher is particularly fascinated by the hold that movies maintain on the popular imagination in this regard: Excerpted films here include “A Nightmare on Elm Street,” “Jacob’s Ladder,” “Natural Born Killers” and the largely forgotten 1989 Christopher Walken alien thriller “Communion” — all of which deal in imagery similar to what his subjects have seen in their visions.
It's fascinating material, linking A Nightmare on Elm Street and Insidious , among many others ( It Follows would be another), together as visions derived from this weird mass nightmare, which is globally common and wide-ranging enough as to potentially serve as a gateway to revealing more about subterranean human fear.
Ascher also works in the links between sleep paralysis and fictional horror stories throughout time, including movies such as A Nightmare on Elm Street and Insidious, that are clearly inspired by the condition, how they in turn perpetuate certain imagery in a cycle of subconscious association and influence.
The result is that the film is rather nebulous about what it’s trying to say: are these people all experiencing a quantifiable medical condition, or are they all living in their own personal versions of A Nightmare on Elm Street?
Their nightmares are duly dramatized by Ascher, whose canted angles and shadowy silhouettes create a consistent sense of unease, and a cinematic dimension emerges as some of the witnesses invoke A Nightmare on Elm Street as a pop-culture expression of what they experience in the night.
