I've been dreaming about the same person a lot?

You definitely have some strong feelings for this individual, as you think about him quite a bit. What most people don't know is their mind is like a projector, and when your asleep you are still conscious, if you were not you would be dead. But you are still conscious, meaning your brain is still working, its just working in a "slower more dim" mode. So what you think of when you sleep comes out as a dream, but you have no control over thses thoughts because its your sub conscious speaking. Clearly you have very high expectations with this boy, as you envision doing so many different things with him and do not want to lose him, hence the "over protectiveness". He may mean more to you than you realize, and you don't want To lose him. Which is totally understandable, and I think you should def. Tell this boy how you feel. :)
