Alright, just from interpreting your dreams, I believe you have some subconscious trust issues with your parents. Either that, or you subconsciously feel that your parents are abusing you. As for the school, I believe it is just nostalgia; you're thinking too much about the past. Nostalgia can cause your brain to do some funny stuff, including depression and nightmares about past experiences, not necessarily bad experiences though. I've had a couple myself.

Awww, don't be worried! Just don't go back to bed, cuz then you'll have nightmares again. x3

I learned that the hard way *shutters*.
