The tendency of feeling that you lived past through that moment and going through the same experience is something that I struggle with everyday. Usually, it's a feeling that I get that I said thing before, or I have done this thing before. One day, I had a math exam and the night before I was dreaming that I was taking the exam, so I could remember all the questions very clearly. When I woke up and REALLY went to do my exam I saw some of the questions that was on my dream. I was really freaked out about the Idea that I knew the questions before even seeing them. It is a very interesting phenomena to witness and withhold such an amazing theory and to be the lab rat of that experiment.
