An unforgettable experience (revised1)

When I was young, I used to go to the cinema with my family. I did not expect it would have gone wrong. It happened about 6 years ago when I went to see a horror movie at a dreadful night. The movie began as we were seated. I was frightened by the scary scene in the movie and I felt like going to the restroom. Consequently, I stood up and went through the crowd toward the gate of the theater. With the fear I stepped into the restroom but saw no one. However, when I was leaving, a man in black suddenly showed up right behind me. I cried out loud and rushed out. Since I was freaked out, I just could not remember which room was the right one. I chose a room randomly, hurrying to my seat. Yet, the only thing I saw was a strange woman gazing at me with confusion. Then I entered another room, looking for my mother. But it was still the wrong one. Noticing that I looked worried, a clerk walked toward me, asking me if I needed help. I told her what had happened to me and asked her if she could tell me the right room. She was just like my saviour. With her help, I found my mother successfully. From then on, I checked my room number every time before I see a movie in the cinema.
