I didn't think it'd be PTSD as I've had these episodes before being in Iraq, and I've lead a rather calm and relaxing life. Usually this sense of paranoia is associated with a nightmare that was reoccuring but I stopped having. The nightmare would include colors, drastic temperature increases and decreases based on events, and spinning paranoia. Here's basically the nightmare:

I'd be standing in a murky, hazy, blood red color cloudy old High school gym with the bleachers packed away. A silouete of a man figure would appear and start screaming at the top of his lungs my name, repeatedly over and over and over again. The room and all that I could see would spin fast, like standing in the center of a tornado. The temperature would rise and I'd feel on fire. Suddenly the walls at the far end of the gym would appear before my face instantly and I'd be smoothered up against them. I'd feel so close to the walls that I could see every divet, crack, pore, outline and feature on every brick. I felt literally like I was being almost strongly forced up against the wall. At my back, I would sense a female figure approach me, and slightly whisper my name upon the back of my neck repeatedly in a very slow, calm yet morose manner. It felt really cold and deathly, it would raise my neck hair and my body temperature in my nightmare would drop and I'd feel frozen and the area around me would spin repeatedly like before and the wall would instantly be miles away from me while I was in the center of the gym again. This entire nightmare repeats over and over again until I wake up, in fear, and in a cold sweat. I stopped having that specific nightmare though.

But the same distortion of images and process of the episode is familiar. Memories, and real-time concious thoughts will all be distorted, to where if I change what I'm thinking of, it will also be distorted until my mind clears up. I can almost, note quite yet, but I can almost trigger an episode upon myself. If I start remebering familiar sights int begins faintly but stops. I don't think it's a seizure, because I'm not having a physical reaction. I realize that what I'm "day-dreaming" about is not real but it still goes on until I come out of it. I should note that 3-4 times I'm concious when this goes on, where I can only recall maybe 2 times in my past where I was asleep when this happened.
