I've had that high school one too! I was just reading that analysis of teeth dream. I agree alot with the self confidence about appearance and stuff. Also the bit about not being heard as i often feel i am ignored or my voice isn't heard or isn't important. It's weird, cause i get this dream all the time, not as often as some people, but every month or so it'll pop up and i think to myself in the morning.... this is a re-occuring dream yet we still (in the dream) think its actually happening. It's weird, sometimes i wish i could jump into my dream and shake myself and tell myself it's only a dream.
