I wouldn't take dreams too seriously. I have had many dreams where I am female or basically sexless like a Ken doll. Just without the muscle definition. But, I have also had dreams where I am a cartoon/anime/comic character, dreams where I look like a video game character, and probably my favorite weird dream was one where I was a talking dog.
Dreams are often influenced by how we live from day to day, things that we see but don't notice, things we watch/read/etc.
But to answer your question, yes. I have dreams that I am still living as female. I think it is just an influence of a lot of different things. The fact that I am still seen as female outside of my house affects my dreams, I am sure.
