This film is actually connected to In Waking (2017)
This was filmed entirely on an iPhone 7, audio recorded through a Samsung Galaxy s5, and lighting consisted only of a cell phone flashlight, a lamp, and ceiling lights already in the house.
The movie Clarissa is watching on TV is actually the short film Within These Walls (2015), a project Marcus Badibanga helped with, directed by Noah Goldberg and Ben Lascano.
