"nightmare"

I had a dream,
some sort of "nightmare".
******
I was back in high school time and I was about to attend the final exam,
I looked at the paper and I have totally no clue about the answers,
I did not study at all,
it was science.
The most funniest thing was that,
I don't even have a single stationery,
not even one!
******
I told 3 of the prosperities about this dream,
they laughed at me and said "how could you have an exam dream when you are working already?"
Ya,
how could I?
