Precognition Or Deja Vu?

I'm 23 right now, but ever since I was little, I've had dreams that eventually come true. I'll have a dream, just a normal dream, nothing out of the ordinary, and I'll forget about it. Then, maybe days, months, years later, the exact dream will come true. Every detail down to the place, the people I'm with, what we're doing and especially dialogue. The actual event will trigger my memory and I'll get this overwhelming feeling of "Wow, I dreamt this before!" Sometimes the event will hit me like a ton of bricks and other times it's a smaller feeling, just a reminder of my dream. Does this mean that I have precognition? Or am I just experiencing déjà vu?

I've always interpreted these events as what is supposed to come true...destiny, if you will. Is it correct to think of it this way? These events have usually been normal, everyday interactions. Talking with people at work, walking with my husband, writing something down, etc.

I remember one time, my husband and I (dating at the time) were walking outside, holding hands. We turned a corner and stepped up a few stairs and then I remembered the dream I had. It was exactly the same! And I also remember the color blue. He had on a blue shirt when it happened. I had to stop and take a breath because it was such a strong feeling.

My husband is the first person I've ever told about this because I was always afraid people would think I'm a freak. But now I'm just curious to see why and how this happens. I'd like to learn more about it. I'm welcome to any and all feedback!
