My Goodness. Did I deprive myself of REM sleep? I was attacked by a vivid nightmare last night...

I dreamt of having the Psy exam in a school hall, then I was asked to write down the cadidate number. I remembered I wrote a lot for the answers and then when time's up, I realized that the candidate number I had written was wrong, so I asked an invigilator if I could correct it. The invigilator looked like the discipline teacher in my school and she said I couldn't. I was so shocked and anxious at that moment, I mean the concious me in real life, I felt as if the dream was real. And then back to the dream, I begged the invigilator to let me correct the number but she insisted that I couldn't.

And then I was in the hall discussing about the thing with my classmates, another invigilator came by and asked what's the issue and I told her everything. She said she'll deal with it and I woke up.

People said if you tell others about your nightmare, it won't come true. I hope by doing so my Psy exam will be fine...maybe that dream just means that I have some kind of unconcious fear about exam. Well.
