Why is this topic never discussed?
You can literally create and shape a world to your liking and make your every wish come true inside it, becoming a cis girl and living the life you ever wanted with everyone acknowledging you as a girl becomes trivial.
Heck, you can even use it to bypass economic constrains, can't afford x expensive brand clothes? With just a thought you can materialize miles and miles of clothing wardrobes to your liking.
And the best of all? It feels real.
It doesn't feel like a dream, it feels as if it's a second reality you control.
One would think lucid dreaming would be far more popular among trans circles, as you can live a life you were denied.
