My dream Yesterday

Over the last few days I have been feeling that I am not doing what I am meant to do. And I dont want to shove away these thoughts and have, thus, felt considerable confusion. Last night (night of 10th Sep) I had another dream-which I think wanted to point me in the same direction.

In my dream I was back in school, with my Physics teacher of 6-8th standard, Ms. Divya Seth. (she, btw, was my first crush from the teacher community-and others followed later). Getting back to the dream, Divya mam, as we used to call her, was teaching a packed class. I had Hemant, one of my class mates ,with whom I am in no contact whatsoever, sitting next to me. What Diva mam was teaching seemed kinda peculiar too- she was teaching us an exercise to form sentences where the first alphabhet of ever pair of words is the same (something like ,and this aint an example from the dream, "Is India The Top Nation Naturally")

I asked Hemant who was sitting next to me,"Dont mind this, but why are we studying this?". He replied,"To be honest no one in this class has a clue". I retorted,"Then why are you here?" He replied," Well, I didnt have anything else to do. There are students who've moved on in their lives and are studying further, etc. Most of the class present feels that they need to strengthen their hold on this subject-even though the exam, and therefore the necessity for the subject, for this is already over. And again, since they have nothing else to do-they have come here".

I said,"But thats ridiculous, its a stupid reason. As much as I like Divya mam and like being in her class, I wont come to the class anymore because it doesnt make sense to me" And then I woke up.. What does this mean? I feel the meaning to be pretty straighforward but still dont possess the guts to chuck my job(physics class) because it doesnt make sense to find yourself realising that job you are doing is not what you are meant to do.

God-what am I to do?
