Hello Mellissa

Reading your post it seems that the dream you are describing must have been extremely difficult for you and very scary, I hope you are feeling better and recovering from it now.
I think your explanation is a very interesting one and at the end of the day, nobody but yourself can tell you what is wrong or right about your own dream. Dreams are strange and funny things and although some of them are results of our subconscious playing tricks on us, a lot of the time it doesn't really mean anything!
I have had a similar experience recently, being an FTM, I had a dream where I was beating up a faceless woman and after thinking about it, it may just be my mind slowly ridding itself of the memory of that girl.
In your case, although it sounds strange, your dream seems positive as it really does symbolize acceptance in who you really are!
Hope you are well
