My mom is driving me to school. She drops me off on this sort of overpass on the highway. Except, it's not on the highway. There's a bunch of my fellow classmates gathered around and talking. Then I look to the left and see my school just sitting there...on the highway...
Then someone just randomly comes up and asks me to the prom. I agree.
I enter the school, but it doesn't look like mine. I see one of my former teachers (from last year, I always debated with him in class and usually won all the arguments), and I was in his class. It was a class of all girls (including me), and it was odd. The table sat on the ground, and there's pillows all around it that are our seats. Then my former teacher and his helper leave the room and we leave and then go into our sleeping quarters.
Next thing I know, I'm getting changed, and I'm completely naked, so I ask one of my "female friends" (who I'm really not friends with in reality because I have very few friends who are female) to grab my bag with my clothes in it. So she does and I get dressed. However, the dream seems to look through that a couple more times.
Then we're all gathered in my living quarters of the school (I don't really go to a boarding school, btw) and I see this dingy mirror, so I look in it, in that mirror my hair is like it is now. Then I look in the other side of the mirror and my hair is bright purple and white (bleached) halfway down, and some of my hair is gathered up in a pony tail. I ask the other girls what my hair looks like, and they describe the purple. At first I don't think it looks to bad, then I decide it's hideous. I start freaking out and telling the other girls if we can't fix it I won't be able to go to the prom. I sit on my bed exasperated.

Next thing I know, I'm in Computers class. On one side of me, is the boy that asked me to the prom. On the other side of me, is my friend Taylor. I'm just typing away, doing my work in computers, when Taylor suddenly asked the guy that asked me to prom "If I ask you out, will you still take her to the prom?" (gesturing towards me) he looks at me and at her and says "yes."

Then, later, I'm at the prom, and it's dark and everyone's dancing.
Then I wake up.

I also posted this one in my dream diary.

Good for you! Always remember, just because they teach and have a degree, doesn't mean they know everything. I work in education as an aide and I've had to correct or tell something to the teacher they didn't already know and should have, mainly in history and geography.

You mention someone named Taylor in the dream. Is that a girl or guy?

Seeing yourself differently in the mirror is a common dream theme. It can be hair, teeth, or skin and it's something you wouldn't dare go out in public with. That usually indicates self-consciousness about appearance.

Taylor is a girl.
I think it might just be that she asked him because it seems to me that every time I date somebody, she ends up asking them out after I've broken up with them (for whatever reason). But it really does hurt me that she does this.

But this dream, the events don't seem connected whatsoever.
