In
The Master Hypnotist, Justin's
lifelong friend, Jason, hypnotizes him into believing he's a girl.
The mind can affect reality, as Justin slowly becomes an attractive
young woman.
In
All Dolled Up, we encounter a young man who makes the mistake of
filling out the wrong questionnaire. The company behind the website
sends him a shipment of women's clothing and cosmetics he didn't order.
That's embarrassing enough, but the feminine stuff starts transforming
him into a lovely young woman. Against his will, he starts to live
the life that matches his appearance.
