What did my dream mean *10 points*?

It means that in this decision, your family matters to you, and you want to please them with your choice, especially your grandmother and older sisters (getting them the water) You know Christopher better, which makes the realtionship comfortable, but you are also attracted to Dustin. You feel guilty that you also like Dustin, when you feel like you should be faithful to Christopher. It sounds like you picked Christopher at the end of the other dream. Good job. Dream problem solving!
