Looking for horror novels

In 2004, his little sister had read a very interesting supernatural novel. Now, she wanted to find it and read it again. Unfortunately, she could not remember the name and author. She had searched online for a long time but could not find this book.
I am very grateful to you for your generous gifts.
I remember that there are a few rough plots:
1." My " boyfriend and I went to the floor with the ghost. Although we got out safely, the experience was very dangerous." I " was extremely curious and panicked. I couldn't help but look behind me. I was almost dragged by the ghost and couldn't get out.
2. Being chased by a ghost in the morgue, being locked up in the research institute where her boyfriend worked, and finally, her boyfriend died. She had no choice but to find an expert to save her, but in the end, she did not succeed.
3. The last part was that " I " was looking for clues at my boyfriend's research institute when he was alive. In the end, I realized that the computer was not turned off, so I talked to my dead boyfriend on the computer. However, in fact, the person inside was not really " my " boyfriend. In the end, I seemed to understand a little bit of the reason, but I forgot if I had escaped.
This was a long novel, not a school ghost story. In addition, the book had detailed knowledge about the supernatural, such as why that place had become a land of four Yin, and why you should never turn back.
If you have seen it, please tell me. I found it very hard. It's my fault for having a bad memory.
