Dream of exam

I'm in a classroom setting and on the desk is an English exam paper. On the front page is an essay that i should read and answer questions. Unfortunately i fall asleep on the desk only to wake up when the teacher is announcing we should ensure we have answered every question and written our names correctly. I feel pressured and rushed. How I'm i supposed to read the whole essay and answer the questions and it's nearing time to submit the papers. Feeling all the pressure, I'm unable to move past the first question when i wake up. Immediately i feel relieved that the situation was a dream which meant there was no real consequences of failing an exam.
