What is crossdreaming? A crossdreamer is someone who, to a larger or smaller extent, is driven towards imagining and expressing themselves as another gender.
The narratives about what makes gender variant and transgender people who they are, have often been colored by the thinking of transphobic people. These negative narratives are also retold because queer and trans people have to respond to such invalidating theories and rhetoric.
But what if we for once leave the bigots behind and talk about crossdreaming from an independent and positive standpoint?
As I see it gender variance normally reflects some kind of mismatch between a person's assigned gender and experienced gender. This is often referred to as gender incongruence.
But we have to keep in mind that such incongruence comes in different colors and intensities. Some end up identifying completely with "the other gender" (relative to the one assigned to them by society at birth), while others simple feel the need to express sides of themselves that others try to deny them, because this is not what "real boys" and "real girls" should feel or do.
