I'm not trans, but I once had this really long detailed dream about how I dressed up as a woman as a joke and then actually became one. I distinctly remember a part where me and my sister were going to some party and just being so confident and happy. I had some questions when I woke up, for sure. But yeah, I'm not trans. It was a huge mindfuck. I think it had more to do with me looking up to my sister and me having a really bad self-image, so that combined into becoming 'like her', physically.
