What a great result from your dream. I think you are correct both ways with your wondering if they are the reflection of changes that happen inside or they actually cause changes.

Dreams are our own productions, come from our own heads/unconscious and are peopled with who we choose as being meaningful to us in some way. So, it is You who are changing inside but also you causing changes that you can reflect outside!

I wouldn't run out and apply to be on the Tyra show right away though Most changes require a bit of practice to get "good" at them. Just like you have to take driving lessons to become a driver, you probably have to remember you don't have to run away from being judged or when you are afraid and do that a few times before it will get easier and more natural feeling to you.
