I have had dreams similar! I will have a dream and then like 8-12 months later I will have it again but things will change just a bit depending on what's happening in my life.
I practice witchcraft but before I started I had a dream where I found an abandoned house. Months later, after I started practiceing, I had the dream again but instead of it being abandoned two ladies lived in the house and they gave me some things to help with my practice. :]
I also have dreams about different apocalyptic scenarios. In one of these dreams the world was overrun with these shadow demon things and months later I had the exact same dream but with zombies instead. Every single thing in the dream was the same the second time except with zombies.
