You picked something a lot less weirder than you could have. All you had asked for was for your clone to be a female version of yourself with two orders. First, she'd go home and think she's you, and not remember being a clone. Second, she'd obey any orders you give her.
The next day, back in your apartment, "you" wake up. It's really your clone, but she thinks she's you. "You" remember that you walked into some kind of magic shop, but somehow you can't remember anything else. You only vaguely recall walking back wearing just a jacket and entering using the spare key. You realize your body feels funny and you look at yourself. You used to be a man, but now, you have breasts and a pussy and a feminine face and body. Somehow you're a girl now! That magic shop must have transformed you!
You take a shower, examining your new body, and then go into your closet for some clothes. The best you can come up with is a T-shirt and jeans, along with a belt. It won't fit exactly, but it'll be close enough until you can figure out what to do.
Then someone walks up behind you--but there was nobody in your apartment. You turn and see someone that looks just like your male self!
"Let me explain," he says. "I'm really me. You're my clone. I didn't make you a girl, the machine in the shop grew you as a girl. You just think and act like me."
How can that be?
"And by the way," he says, "I'd like to ask you one thing..." You feel that you have to listen to what he says, and obey. You *want* to.
