As the movie Us (2019) came after this one, I'd have to say the inspiration may have been something like Coherence (2013), with a dash of Truth or Dare (2018). Unlike most people I didn't see Coherence as a revelation. I admire the originality of the idea, but from that idea the movie only goes so far as to create acting opportunities for the cast, much like an episode of Thank God You're Here (2006). Similarly, Seven In Heaven is an opportunity gone begging. It hasn't the abrupt violence, distortion and frantic tension of Us, or the dystopian dimension. The tension in Seven is blasé, and even a little illogical. The cover of the dvd puts one in mind of Paranormal Activity: The Ghost Dimension, but Seven lacks any special effects at all. Nor did Seven have the visceral horror dimension of Truth or Dare. These points are all opportunities that have gone begging. The writers and filmmakers needed something much more ambitious, hard edged and visual to really make this source material sing. It needed more time in the think tank. I thought the ending was a little cruel. That was what decided me to give this only a 6. I was certainly entertained, the premise and the actors did display skill, but I think that most people over the age 16 may think this movie a little tame by today's standards.
