"The Signal" starts out a bit vague, but then the plot sets in. They manage to set everything up so that you can't be certain whether it's real or imagined. I read that the movie is partly based on Plato's Allegory of the Cave, in which people see a limited reality (also the basis of "The Matrix").
Laurence Fishburne's enigmatic professor is the best character in the movie, and Lin Shaye's* aging character. "The Signal" isn't any kind of great movie, but I thought that it was OK. Mystifying, more than anything. A similar movie is "The Quiet Earth" from New Zealand.
*She also played the sunburned neighbor in "There's Something About Mary" and the retiring flight attendant in "Snakes on a Plane".
