Strange Going-ons??

Hey, i was talking to AdamA the other night about lucidity and all that and we managed to figure out what kept re-occuring in my dreams so i could use it as a basis to recognise and maybe do some RC's or what not, i said to him that my dreams are mostly at school (unfortunately) and they always take place outside of school or in th playgrounds, and never in a lesson, now i've been doing a certain RC of my own as a test to see if i can do it. Now though last nights dream was vivid like most of them are for me i was outside school and in the playground, however in this dream i actually was in a lesson,in a classroom which i said i'd never had before! I don't know what brought this into the dream.

It could have been two things, it was a revision lesson for english in the dream and yesterday me and my mate Andy were chatting on msn about these revision lessons and how you get told where to go and you go, and then in the dream there was a list, we got told where to go and we went, it could have happened because i told AdamA that i'd never had a dream in the classroom, i didn't enjoy it but its asthough any of my attempts so far to become lucid are being seized by my subconsciouss thoughts, its asthough my subconsiouss see's my plans and changes its plans so that i can't become lucid, i can't exactly predict what i'm gonna dream about either. Could anyone offer me any help on what to do, thanks alot. :)
