Bizarre something that needs the Oracle's help :/

No one seems to be on here anymore, but this dream still bothers me.          

My friend and I are somewhat in our school, only enlarged and sorta changed in some way. She and I carried handguns and were panting as we walked down the corridor. Then, we turned 'round a corner and came upon our classroom. There were no students at school, since everyone turned to zombies and my friend and I are the only remaining survivors. But when we opened the door to our classroom, a lower grade student was there, and our music teacher was also there, giving him a lesson I can't remember. Then he left as my friend and I entered. She was about to leave when I told her, "Uy, andali lang. Kokopya muna ako lecture!" Then I took a notebook from who knows where and started copying the lecture written on the board. She set down the handgun and copied the lecture as well using a notebook and pen from who-knows-where.

See? It's bizarre! I shared this with my friends and one of them asked me, "So . . . you dreamt of us in World War Z?" And they were looking at me like crazy--ahem, ahem, I am! What d'ya think?
