I Am the Only Normal Person in Time Travel

It's a very old story. When I was crossing the road with my dear sister, a big truck came speeding towards me. I tried to save her, but I died. I woke up in a trance. I clearly felt that I was dead at the time, but now I am still alive. Have I really traveled through time? I looked around. I was in the hospital. My head was in a trance again. It seemed that I had merged with the original owner's soul. Of course, I also got the original owner's memory. It seemed that the world was not as ordinary as it seemed.
