What does this dream mean? ?

I've been dreaming lately like three tomes that I'm really really thirsty, and I chug down water bottles and that water feels so good and satisfying..when I wake up I'm thirsty and get up to drink water and I've been being a lot thirstier lately, not at school bit just at home. i just got braces but I don't think this is the reason for this and I've ne'er really drank that much water and even know that Im really thirsty I drink no more than 2 water bottles a day.
