What is the meaning in a dream of arousal

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.

I'm riding on a carousal standing with palm trees around me, water below me and stars above me. I'm very dizzy and can't find a way off.

I was kneeling at my professor's feet, and she wanted to try her bra on me, reaching down over a short wall. I was totally embarrassed by her attention. She kept staring at me in a sexual way, and forcefully tried to put the bra on me, over my clothes. I held my arms down at my sides, but she tried to force it down, over my head, with it still clasped. It hurt. Finally I thought I'd get it over with, so I agreed to try it on, and I took off my shirt and tried to put it on properly. Once I took my arms away from my sides, I felt her coming down on me, and I was intensely embarrassed. The more she stared, and the more she talked, the more embarrassed I became. Other people were there. She scolded me. I felt shame. I realized I was almost naked, except for underwear. I never got the bra on. I found myself laying down on the floor, in extreme sexual heat, twisting and turning. One boy stood there and watched the whole thing, making me more embarrassed. I woke up struggling against her sexual advances, in terrible discomfort and sexual arousal, moaning and struggling. I was ashamed. I was so hot and turned on, while being uncomfortable. I was so embarrassed, and it felt so real.
