I dreamt that I was designing a house for the controller of a power plant that produced heating during cold months and cooling during warm months. It was connected to a town by a bundle of shiny pipes. As the plant itself was warm while it produced heating and cold while it produced cooling, I placed the house right in the middle of its flat roof. In cross-section, it was right in the middle of the roof, as well. One half of it was above the roof and the other half below it. The house had windows looking both above and below the roof. The windows looking into the plant itself were of the same size as those looking out. The symmetry was pleasing in drawings. I remember being quite happy about the elegant way in which my design dealt with both heating and cooling of the house. Also, it did not take any additional land next to the plant. When I woke up, I realized the windows looking into the plant would not be very pleasant to look through. Even the controller would get tired of looking at the power plant all the time, let alone the controller’s family.
