I agree that this song is about prostitution. The whole changing her name thing and being in someone else's dream is the girl playing the part the man wants. The phrase, "the car is here," references how prostitutes are often picked up in cars. A dancing girl is not a prostitute, but still sells her body for money, only it's by stripping, not sex. I think the part about being a soldier and not crying is about being strong despite the horror of having to sell one's self for money, which I'd guess feels as bad or even worse than being raped because a girl feels she has no other way of surviving other than allowing men to use them.
