I was raped by my best friend a few years ago. I was a virgin then, and still, years later, I can't seem to "go all the way" with anyone. How can I stop freaking out and messing up relationships?

Sometimes at night I'll have a dream, and then it'll happen! There's no knowing if or when it will happen, but if I have a realistic dream one night, it's bound to come true at one point or another. For example, in first grade, I dreamed that I was in a place I had never seen or been in my life. I didn't even know it existed. Then, in third grade, I walked into the room that I dreamed about in first grade. It was the computer lab of my new school. Or I could be walking down the street and meet someone I have only met in a dream, in the exact same scene as the dream. It is all very confusing, and I think it may be either some sort of precognition or a mental disorder. Could you please tell me why this happens?
