What do my dreams mean (this is sort of tough)?

In basically every dream I've ever had, I've always been a part of something larger than myself. Sort of like how secret agents feel, I suppose. I've always been included in some large plan that could change lives forever. For example, I once had 4 dreams in 3 nights that was a story-line. The first one, I was captured because of some power I had, but I didn't know what. The second one, I was thrown into a big place resembling a slave trade or asylum (we were given shackles). The third one is where I was brainwashed for an upcoming war or something, and the fourth is where I was sent to kill someone. I've had many dreams like this, including the supernatural, villains, and even real-life situations, where I feel like something big is happening, but I don't know what. Or I DO know what, but my dream never reveals it. I've also had multiple dejavus over the course of my life, one even predicting the entire year. I want to know, because my mom isn't as good at dream-reading as she thinks she is, what do my dreams mean? And no, I don't do drugs or drink, so please cut it with dumb answers.
