I wouldn’t ever presume to analyze the dreams of strangers. However, many dreams reflect your feelings and your fears. (Others help you solve problems. I definitely prefer those.) So think about what rape represents to you. It sounds like you are feeling helpless to stop someone hurting you in your daily life. But how many, or who precisely, really varies. For example, for about a few years of my life, I used to dream that I was in highly dangerous situations — revolutions, mostly — and couldn’t find my contact lenses. I couldn’t see to protect myself or escape. This sounds like an obvious one to analyze, but it took me some years to realize that, while it certainly spoke to my wanting to be able to see, it was a lot more about being trapped in situations where nothing made sense and there was a lot of danger I didn’t understand. I’d guess rape has some of the same meanings to you. But don’t assume there’s one way to interpret any dream event — they’re your unconscious trying to communicate with you, so the meanings are person-specific
