Dreaming of yourself?

I have experienced this twice. What I gathered from what I saw coming to pass is my future self showing up. If you are in transition, have any vices or people you are trying to let go of, or an immediate goal to attain, I say that's probably the outcome.
To figure out what it is, consider something that is present in your day to day life, like a relationship, your job, or a hobby.
