This is the question that most people mean when they ask "Do you really believe you''re a dragon?" -- and there is a misconception that all people aspiring to draconity expect someday to sprout wings and scales. This is not universally true.
Many people are dragons spiritually, and that (more or less) abstract connection is as far as it ever gets. There are also those in the dragon community who believe that in this life they are humans, but in the past they have been dragons, and that draconity is a "more natural" form for them. Of course, there are dragons who expect within this lifetime to regain dragon form, and there is not anything wrong with that, either.
