It is most likely your spirit guide contacting you, or it could be many different things. It also could just be a coincidence, or it could have signifigance as some people believe that dreams are our natural way of expressing how we feel about things we want but either do not have or cannot get. Also some people believe that dreams are a way of working out subconscious issues and conflicts, things you suppress or don't think about consciously because you don't want to, or maybe its traumatic. In anycase we can only state our opinions on the subject since we don't really know you on a deep personal level nor did we actually experience this dream oursleves.
Best of Luck,
