Ok I don't usually do this I usually can interpret my own dreams but this one has me stumped  
                 I was a dragon (not sure what color and I don't think it really matters). A man came in so quietly I didn't hear him and he had two young people with him. I sniffed and knew they were vampires. He asked me to watch over the young people so I spoke with them. The male was mentally challenged ( physically 20 mentally 13), the girl had been in a wheel chair but could walk now, however she was very naive and innocent about the world and how it works, I agreed to take care of them. and then someone woke me up the dream didn't end properly it was left hanging.
