An insomniac student is haunted by a demonic figure in this flamboyant and stylised waking dream of a film

There is something visionary about this near-nonsensical, kitsch but atmospheric techno-thriller from Canadian director Anthony Scott Burns. Drawn along on dark somnambulic rhythms, it incorporates elements of fantasy, horror and 80s synthwave aesthetics without giving itself over completely to any of them.

A wordless first 10 minutes introduces us to Sarah (Julia Sarah Stone), a runaway student apparently unwelcome or unwilling to return home, waking in spectrally lit parks and falling asleep in coffee shops. Dropping suddenly into surrealistic CGI dreams that track inexorably towards a demonic figure who, if approached too closely, wakes her with a start. Sarah decides to try and climb out of this insomniac bath by enrolling in a university sleep study. It is overseen by Dr Meyer, a Cronenbergian academic in big glasses, but run by a trio of researchers who, like the memory technicians in Eternal Sunshine of the Spotless Mind, have a loose relationship with scientific protocol. Becoming close to Jeremy (Landon Liboiron), she learns that they are using pioneering technology to observe the subjects’ dreams – and that the same shadowy presence manifests in all of them.
