wedding dream

Aren't you supposed to wait until you're engaged and have been actually planning to have wedding nightmares?

Last night I dreamt that I was getting married - right then. I was in my dress and about to walk down the aisle, but I was surprised by it. In the dream, Mr. L had said something offhand, like"we should get married" at some point, and I had blocked it out/not remembered, but here I was, and we were getting married. I was just about to walk down the aisle, but I had no idea what awaited me. I didn't know who was there, or where we were, or if we were even having a reception. It was strange.

I wonder where it came from? Is it from too much almost-planning, or feeling like too much is unknown and out of my hands? Or something else altogether?

Perhaps the strangest part about it is that I've been very relaxed lately, and non-obsessive. I've honestly just been enjoying his company and enjoying where my life is right now.
