The idea of an external origin of dreams rather than just within a person’s own consciousness is taught in the Bible, both in the Old and New Testaments. From Jacob’s dream of the ladder rising up to heaven to Pharaoh’s dream of the seven healthy and seven sickly cows to Nebuchadnezzar’s dream of the great image to Joseph’s dream to flee with Mary and the baby Jesus into Egypt, there are dozens of incidents involving numerous people in the Bible in which dreams were sent by God to serve His purposes. As a matter of fact, in the book of Job we read that dreams (and visions) are a teaching tool employed by God to speak directly into our subconscious.
So from a Biblical perspective, dreams are a communications tool, using dreams God speaks directly into man’s subconscious. The Subconscious of man is not necessarily different than his Consciousness. The subconscious is merely his consciousness when his body is in a state of sleep. In a waking state, information is inputted into the mind from external sources through bodily organs. One hears or sees or feels through bodily means, information arrives through sensory inputs. I believe the body interferes in pure communications with external information sources such as God or Satan. This is the reason why mystics rely heavily on ‘Sedation’, as did the characters in the movie. Sedation reduces or eliminates interference from the body, allowing direct communication with the person’s mind. The greater the access required to the person’s consciousness, his mind, greater the amount of sedation that needs to be administered. This was the reason why in the movie the three level dream state could only be achieved through the use of powerful sedatives. Powerful sedatives that are usually narcotics, like Morphine, also have powerful, negative side effects.
This is the area in which God’s communications with man, and that of Satan are distinguished. God does not need to chemically sedate people in order to communicate with them. He can anesthetise man’s body, cause him to fall into a deep sleep, without the use of harmful drugs, as for example with Adam when a rib was surgically removed from his body in Genesis 2:21. And the LORD God caused a deep sleep to fall upon Adam, and he slept…. Satan, on the other hand must sedate his audience before he can enter their minds unhindered. This was the reason why the dreamers in the movie could enter into the victim’s subconscious could only after heavy sedation. This is also the reason why all satanic tribal ceremonies make heavy use of natural hallucinogenics, and why powerful chemical hallucinogenics such as LSD are frequently used in Satan worship ceremonies by the powerful elites in our world. God’s reasons for communicating with man through dreams are for man’s own benefit. God instructs him, God guides him, and leads him away from destruction through dreams, among other methods that God uses to communicate with man. Satan, on the other hand uses man to satisfy his own ungodly desires just as the protagonists (the criminals) in the movie did for selfish reasons, for money, stealing without being concerned for the loss and long term negative effects on their victims. God’s dreams can be instructional, as for instance when Joseph was warned to flee from Israel into Egypt, or they can be prophetic, as for instance Pharaoh’s dream of coming drought and famine. Whatever the technology employed in the movie to create dreams, it is a Biblical fact that intelligences and consciousnesses, other than that of the dreamer can access the sleeper’s subconscious and project a dream movie on to the screen of his mind.
