Dream of building, screen, sexual

I dreamed I was involved in the plot of a horror film. It involved a haunted house, or abandoned house, where I supposed awful things were to take place. I walked by what I looked to be this haunted building, only it has been transformed into a large department store. I think this is a neat trick, it will attract people whom it can submit to its horrors. I walk in and look around. Everything looks normal, but I am waiting for something to scare me. But, then, the thought occurs to me that this is a nightmare, and therefore I should face anything fearsome. This thought radically changes my outlook, and with an open and curious attitude I turn to the scenery, now floating along, looking for challenges and anything interesting. I note that some people are operating a video camera at one side of the room and the video screen is on the other side. I am intrigued by the idea of getting my own image displayed and orient myself in front of the camera, while looking at the screen. The idea becomes sexual and I wanted to display myself on the video screen. At first it was a struggle to get the screen to display anything other than my back from the waist up fully clothed. Eventually, I got the right zone on the display and begin to remove my jeans. I begin to experience sexual arousal which intensified quite rapidly and within five seconds, I had a wonderful orgasm, the first I'd experienced in two months. I awaken immediately afterward feeling satisfied.
