Alexandra,
I was told by a psychoanalyst acquaintance that we play all the parts in our dreams. So, you might look at your dream as showing that sometimes you like yourself and sometimes you don't; that like with all of us there are some things you like about yourself and some things you don't. And that you are uncomfortable being 'naked' psychologically/emotionally for others to see, even for yourself to see.
Just my thoughts. I hope you are feeling much better today.
