If you have ever heard the story about the military and Montauk you would see the similarities. In the Montauk story they use a device to realize objects which appear and develop some solidity for a certain period of time. But at one point in their experiments a creature appears and a windstorm around the facility. The creature starts to do some damage and they have to get it to go away.
In this movie an injury from a lightning strike might be to blame for things coming to life and being under the control of people. It is clear in this movie that one of the characters is very nasty and quite sociopathic towards the other character. Childhood issues boil up between the people. Then to their surprise affect people in a different part of the world. While one is concerned and horrified by the damage done. The other person is quite sadistic and enjoys the trouble that is caused. Eventually the two people confront each other. Later the damage is reduced and the creatures stop.
