I had a doozy of a dream last night.
In the dream, I was a military specialist in getting information from terrorists.
So we took an old underground missile silo and built multiple cells in it. Each cell was very heavily insulated so that someone in one would never know that he wasn't completely alone in the world.
Each cell was also quite large. As large as a large one bedroom apartment, but with no apparent door. Think about the ending in the movie 2001: A Space Odyssey, but without the fancy statuary:
Also without the monolith. Everything in the dream was white with very little contrast.
There were hidden cameras to view the prisoner as well as hidden microphones and speakers. The prisoner would never even see guards. In the day, the lights were on for 15 hours and then they would go out for 9 hours. That 9 hours would be totally dark except maybe for some faint light to help him find the cracker and some soft light for an hour in the middle of the "night" to stimulate an old time first sleep / second sleep pattern.
There was no tv set. Also, some carefully controlled reading material.
Over the hidden speakers would be played very calm music and religious (not necessarily Christian) discussions, but only in the daytime. Also, someone with a very calm and smooth voice would engage the prisoner into religious discussions. It would be available at regular times of the day as well as any time the prisoner clearly asked it a question. Of course, the prisoner might not get an answer, especially if he ventured outside of the standard topics.
The goal would be to build up a rapport with the prisoner and to encourage him toward a different and very peaceful religious view where he would eventually renounce his old lifestyle and provide information about everyone involved as a confession.
Also, the food, especially its flavor and spiciness, would vary depending on how well he was cooperating. The more peaceful he was and the better he cooperated, the better the food.
Also, there was a clock/calendar on the wall, but the calendar changed slowly. The prisoner saw each day as repeating for several days, especially when he misbehaved. Each day that the day stayed the same, the music and religious discussions played over the speakers remained identical. Also, the food would be identical.
The dream was about a prisoner who had been captured unconscious and who was put into the cell still unconscious. He went to bed somewhere in the Middle East and then woke up in the cell. He never saw his captors at all or even knew he was captured.
