Younger girls dream of meeting/dating a celebrity. Young boys dream of having a giant robot to smash things.
Women dream of getting married and having a family, men dream of making making something a gallon of gasoline explode in the backyard of that house, or
shooting a tank of propane that's on fire. The nerdy ones build railguns in their garage.
I'm not really seeing the problem here...men have lots of dreams that women can't possibly understand, mostly because they're really impractical, risky, and on occasion, just plain stupid.
Like becoming a mangaka instead of focusing on school.
