Dreams about boys....wow. Who would ever expect a teenage girl to dream about boys? <br />
As zygote said, it's called puberty............but don't expect it to stop when puberty ends. Women dream about men. It's natural.
Flirting <br />
To dream that you are flirting or that someone is flirting with you represents your need for intimacy and affection. You may be about to enter into a serious commitment or relationship in the near future.<br />
Just enjoy your dreams...
