The Brain Machine (1972)
Plot: A group of volunteers arrives at a remote, high-tech laboratory for what they believe is a scientific study on biofeedback, mind-reading, and memory enhancement. However, the experiment is actually a front for a top-secret military project involving a powerful computer known as "The Brain Machine." As the subjects are hooked into the system, the computer begins to take control, digging into their deepest traumas and psychological scars. The experiment spirals into chaos when the military hijacks the equipment for more sinister purposes, leading to madness, accidental deaths, and a catastrophic electrical surge as the subjects fight to escape the machine’s mental grip.
