What is the meaning in a dream of desk

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.

I my dream was in japan in a hotel. While i was in the hotel desk I new I recently won the lottery. Then in another dream I was in the bank managing my money after recently having won the lottery. Then in another dream I was checking my lottery ticket and the web page would flash in red color because of the big amount I just won.

I was asleep and i was trying to wake up each time i'd wake up i'd later realise that i am still asleep and that  this is just another dream i woke up again and there was 2 of me , i could see everything from a third perspective as if i am watching a movie the old me from the past was sitting in a chair infront of a risk with what seemed like a very modern computer , thr room was spacious and dimly lit and old me was trying to control me by using the computer telling me to wake up but old me couldnt get me to wake up so future me showed up and sat on the desk saying wake up wake up wake up and present me in thr dream could hear their voices in my head but i still didn't wake up, i couldnt i wanted to but i couldn't but i kept on trying till i actually woke up
