For some reason or another, through external influences in your reality or environment, something attracted your mind to the idea of being Rebel instead of Imperial. There could easily be genetic influences as well. It also depends on your imaginative and creative processes. If you find it more endearing to live a life you would want to live in this mythical universe, and are generally a good person, you would be more likely to choose rebel. If you're the type of person who wants to pretend to be bad, you'd choose imperial, even if it had no bearing in your reality. That's why some males don't mind playing females, but some guys can't stand it. It is strange though, how women have little preference.
Why was I born in Denmark?
When do they invent the teleport machine for real life?
The first question is tough, because it all depends on how you define "I". Are you your body? Are you your genetics? Are you your consciousness? All in all though, YOU weren't necessarily born in Denmark. I only say this because most people define themselves as how they've grown personality wise.
If you wanna be purely technical, it's because that's where your parents decided to birth you after having, probably a ton, of crazy sex. This would be the case if you defined everything in your being as just where your body is. Which is probably what I would think. So you were born in Denmark because of your parents choices and the coincidence that they met, and the particular sperm that carried your traits happen to win the race.
I'm not sure what you mean by "real life", but there are a few time / inter-dimensional machines in the making. Obviously, no one knows if what they aim to do is even possible, but they are being created.
See, now these are better questions.
