I keep having this dream and I want to know what it means.

I often have this dream, but I had it last night and figured I'd post it. Here I go!

I'll be somewhere, maybe home or elsewhere, this is the account from last night. I was at a school that slightly resembled mine, but not much. But it was like the city from Planet of the Apes (The Tim Burton one) and it was daytime. I was doing a report on an endangered animal, but I had to ask a noDC to make sure that was the real assignment. I was ding it on a type of ape. Let us take note that I have been out of school for a while now.

So the reoccuring element in alot f my previous is me doing a project or assignment last minurte, which I do in RL, and I wake up worryng about finnishing it, leading me to believe that I did not finnish it.

Here is my interpretation, tell me if it is right (I am training my Dream Interpretatin abilities):

Not being where I would do work- Me felling out of place
Working the day before it was due- Me needing to not cram things and work harder and not rush things
Asking a DC to reassure my understanding of the project- Not being sure of myself, feeling stupid or unreliable
Waking up worried and the project unfinished- Leaving somthing unfinished, and being unfinished.

So, am I right? Is this a normal reoccuring dream? Would you call this a "nightmare"? And how can I use this to get lucid?
Thanks, -Reality

I had this dream on vacation, just wanted to add
