So I keep having nightmares, and recently I've started noticing my teeth hurt when I wake up, possibly from grinding them when I'm sleeping but I'm not a anxiety grinder or anything. The nightmares tend to be about my car getting damaged or some family coming to live with me again. Neither of these are real concerns, I'm happy as well, I don't get why I keep having these nightmares, almost daily. I'm 24, happy, life is fine/good. So what gives :\
