I have a movie idea and am wondering if it is one already.

There is a new headset available and the usual hype comes with it. it is not associated with any known brand. It works great and gets rave reviews.

However, after using it for a week or so, people start having nightmares whilst they are awake. It starts off where in a gross ugly parking lot, people might see a lake and meadow from the game they were playing for stress management. Then amusingly, they will see some flying armadillos infiltrate their boring jobs.

Then the horror games take over. Monsters appear to people while they are walking down a dark corridor or alley.

Next phase...The images become real and start damaging and killing.
