I just awoke from the scariest dream. I was running through the stairwell of a building. I think it was one of the dormitory buildings from my university, but it was different and a little unfamiliar.Someone was chasing me but I didn't know who or why. I just knew that I had done something terribly wrong and someone was trying to kill me in revenge.
我被一个很可怕的梦给吓醒了。我梦到自己在一栋建筑的楼梯井跑着，好像是以前大学的一栋学生宿舍，可是不太一样，看起来有点陌生。有人在追我，我不知道是谁，也不知道他干吗追我。我只知道自己闯了大祸，有人要杀我报仇。

At first I just felt anxious, but it turned to pure fear as I tried to get out of the stairwell. All the doors were locked. I ran to the top of the stairs and there were two last doors.
起初只是担心， 后来想跑出楼梯井时已经变成全然的恐惧。每扇门都锁住了，于是我跑到最上面的楼梯，那里还有两扇门。
Somehow I knew that behind one of the doors was something awful and frightening, but I didn't know which one. I trembled and froze on the spot. Then I heard someone coming up the stair closer and closer and I lunged for one of the doors, praying that it wouldn't be locked.
不知何故，我知道其中一扇门后面有些恐怖的东西很吓人，只是不晓得是哪一扇。我就这样愣在那儿，一边还在发抖，接着又听到有人上楼的声音，离我越来越近。我暗自祈祷门没锁，就往其中一扇门冲去。
The door opened and I ran through it. All of a sudden, I was falling through the air. My heart jumped and I woke uo i a cold swest. It was only 4 am, but I got up because I was too scared to fall back asleep.
门开了，我也冲了进去。突然间整个人开始往下坠。心脏猛地一跳，我醒了，吓出了一身冷汗。虽然才凌晨4点，但我已经被吓得不敢再回去睡，只好起床。
What do you think ot means?
