How I've looked and presented in my dreams has shifted a lot over the years. I'm afab detransitioning woman. Back in my transition when I thought of myself as guy, my dreams always portrayed me as how I looked at that time irl. Meaning when I was pre-hrt but presenting male my dreams showed me as such, when I was on hrt and passing better as male my dreams showed that too, and when I was post-op top surgery my dreams reflected that. They syncronised with reality, pretty much.
They did however, never show any hints of the dysphoria I experienced when awake. Only twice I dreamed of having a cis male body, one of them was a nightmare and portrayed me as an adolescent rapist. I often get nightmares especially focused on sexual abuse on both sides of the fence, because of my past traumas, so that's not new or rare for me, but that particular dream was especially abhorent because it seemingly turned my "dream body" into something negative. The other cis male dream I had was just me taking a shower and inspecting my... erhm yeah, dick. It was a better dream but mostly just weird. Like I was fascinated but I didn't relate to that body as my own.
Now in my detransition which began just 3 months ago, my body much remains the same irl still, except that I shave it, but my dreams show something much different. Now they show me as how I want to look, with breasts again, with a naturally smooth body and looking like a woman also without makeup. They even show me with my hair being long and thick again. And they show me all that in a positive light. I had one such dream quite recently in which I was running around topless and I was making out with several other women who also ran around topless. It was just mildly sexual and very sweet and feel-good, which was a rare kind of dream for me.
That dream reflected both my detransition goals and that I've recently accepted my bisexuality after many years in denial. It reflected me finally starting to come to peace with myself. And it was a rare kind of dream cause I'd say around 90% of all my dreams are nightmarish, dark, filled with heavy negative emotions and various kinds of abuse. I'm used to them now though and handle them well, but that doesn't make them nice.
Previously in my detransition my dreams have mostly portrayed me as a troubled and broken, masculinised woman. As me being perceived as "fake" or not taken seriously by others, and as me being very insecure about my body mot looking or feeling right. And they have also portrayed my discomfort with my flat chest in painful ways. So that shows my dysphoria that I also feel when awake. That my dreams show my now reversed dysphoric feelings but previously did not show my original dysphoric feelings, I take as an important sign to what's brewing under the surface of my mind. Not as proof, but a sign.
I think dreams often show both our subconscious and conscious feelings and mix them together, which can provide rather confusing results. I'm no expert on interpreting dreams in general, but I've become rather good at interpreting my own dreams. Each mind is unique so the meaning behind your dreams is unique to you. Making a dream journal could actually be helpful for you to understand them better. That worked great for me in the past. But I'd say that your dreams do likely reflect some suppressed feelings and them showing you as a woman so much probably means it's an important message that your mind is trying to tell you. But exactly what that message is, I can't tell you.
It also sounds a bit like your dreams are lucid dreams? Meaning you can control what happens in them. If that's so, you're probably subconsciously expressing an emotional need in them. When I've been lucid dreaming I do things in the dreams that I may not have wanted to do when awake. Like for example I may choose to run away from a difficult situation while dreaming, but irl I would have prefered to stick around and sort it out instead.
Okay this became long but, dreams are kinda complicated, and I don't think they should be taken as literal. Usually dreams are more metaphoric or figurative in what they portray. It could be a sign you want to transition and live fulltime as a woman, but it could also mean something else. Like it could be seeing being a woman as an escape/coping mechanism, or as a metaphorical way to break free from something in your life, to show some in general feminine aspects of you, or expressing your feelings in some other way.
