Note: "San Andreas" is reviewed on my "Films on Major Threats to Freedom" blog May 30.
Update: Aug 24, 2019: Here is a discussion from TIFF of how the SQUID technology in the movie works. The subject wears a hidden device that records her sensation. Then a second person who gets the headset player ("Google glasses" or something like Ocular VR used by NYTimes 360degree films) can recreate the sensation, and that could cause brain death if overdone. Wikipedia explains it here. There is also the idea that someone can be "upset" if exposed to certain documents or ideas or images (New Zealand incident.)
