Couple of questions - possible dreamsign and recurring dream theme?

Hi.
Recently I've been having lots of dreams involving exams or lessons. I've got exams coming up soon, do you think the recurring dream theme is related to this? It's not worrying me, I'm just wondering whether it is or not.
Also, yesterday (or this morning? Night-time times confuse me...) I had a dream involving the centre and candidate numbers changing on the front of the paper after I'd wrote them. It's the 4/05/09 entry in my DJ. Is this a type of dreamsign, a variation on the one where text changes after you've seen it once?

When I wasn't in school over spring break almost all of my dreams were of me at school.
It could be a dreamsign :/

Its BLATANTLY a dreamsign! :) pretty good one id say... before bed tell yourself "My exams arnt for awhile - The nextime im in an exam I will be aware im dreaming" over and over... You should be able to get lucid pretty easy with this dreamsign.

And the changing text Id suggest you use that as a daily reality check whenever your studying or what not, since you already noticed the change within your dream.
