What could my dream mean?

Kristina • Getting married on 6/20/16

So I just woke up from a nap and I had a dream that kind of freaked me out. I only remember bits and pieces.

I was on the deck of the house I live in, and somehow I end up falling off and hitting my head landing in concrete (The deck is quite high up). I wake up in the hospital and everyone is worried but I insist I'm fine and leave the hospital.

I know its not much to go on, but do you have any ideas?
