I met Déjà Vu today

Due to the attending lecture tomorrow, I went to the classroom first in order to know the location. The lecture I will attend is an Engineering class because it is my major in the future. As soon as I arrived at Engineering Block, I found everything was so familiar to me, yet I was 100 percent sure that it was my first time to visit this building. Afterwards, I tried to find the the right class room which lies at the third floor. By the time I was walking on the steps, I felt surprised!! It was just like happened before and hard to remember the date. Then I got the classroom-----Oh my GOD!!! Exactly the same, I was quite sure that I underwent it and I checked some details such as the color of the door, also some other items near the classroom,

same, same but really cannot remember when it happened,so weird!! On the way I was back home, I still thought about it but no result. Perhaps it was Déjà Vu.

I heard Déjà Vu long time before; however, I did not believe it, for the statement is fake. Now I do! I found this phenomenon is based on a certain theory. I think everyone, because of our age, has met Déjà Vu, so do not feel strange next time, just for fun...
