Dream About Unknown City And Gurus

I had a dream that I was in an unknown area where it is closed to space, like only five pots were there and each pot there was one guru-like, teaching a seminar, spiritual-like, and everyone goes. And when completed, they give food and other tasks, only for working only we can live there, and we can give according to, and after completing five, only we can go out. The lightest type of dream reflects in different types in a closed, unknown city where we have to finish work and we can go back. What does this type of specific dream indicate, sir?
