I've had dreams as well that were predictions of future events. That being said, I never read too much into the details, because they are not always 100% correct.
I used to have reoccurring dreams of breakups before they actually happened, and I think some of my past relationships were affected by that. However, the details in the dreams of the breakups were not always spot on.
It's possible that you will get into an accident and be rescued by a handsome stranger who will become the love of your life, but it's just as possible that it won't happen. I see it being more of a possibility than a definite reality.
I believe that while we have a path set before us, our actions can alter that path without us even knowing things have changed.
In either case, my opinion is to just live your life! Don't live in fear of this possibility. For all you know, that fear could be what changes the path and keeps you from meeting this possible soul mate from your dreams.
