i dreamt i am in public restrooms twice this month. both times there is a window where people can see the top half of me. the second time a woman comes in with her little girl.

The meanings of the symbols in your dream should help explain why you had it. Here are links to their definitions on this website:

bathroom: dreamdoctor.com/dream-dictionary/definitions/bathroom.html
exposed: dreamdoctor.com/dream-dictionary/definitions/exposed.html

The woman and her little girl in the dream may be symbolic of people you know who may be "invading" your private space. Children in dreams can have additional symbolic meanings which can be found at this link: dreamdoctor.com/dream-dictionary/definitions/exposed.html

Hope that helps!
