So in this dream a five or six story building was collapsing and some super hero dude swoops in to save the day and rescue the damsel in distress. Just so happens the only costume the super hero dude is wearing is a cape... yep, completely naked otherwise. But you know, manly body and all that, standing there hands on hips.
The heroine is appreciative for being saved, and picking herself up, being at waist height totally checks out his vulva (and I think she likes what she sees!). That's right, super hero dude has a vagina but he is totally male. In the context of the dream he wasn't trans man, he was... a man with a vagina. Within the unspoken "dream logic" this all made sense, apparently superhero dude wasn't an anomaly, the genitals you were born with were not what determined being male or female - apparently there were plenty of guys with vaginas (presumably plenty of women with penises).
At that point I woke up which means I remembered the dream in all it's glorious detail (I can do that) and it has seriously bent my brain. I mean, I think it's a great dream - but there's a much deeper analogy/metaphor here which I had hoped writing the dream out would bring to light. No luck so far!
I guess at the core of it, it means labels and preconceived notions are meaningless. Imagine if when a baby is born the first thing they say
isn't "it's a boy"/"it's a girl"; or, when asked about the sex of their newborn parents said "that's up to them, wait until they're older and and ask them yourself!"
Of course, it could have all just been a weird dream, I have lots of those.
