I was abandoned in an abandoned public toilet by the singing of a plate rolling machine. When I woke up, I felt like I was drunk, staggering. Just as I was about to walk out of the toilet door, my grandmother walked in (my grandmother has been dead for 15 years and I have never dreamed of her before). She cried and hugged me as if I had just gone through a life-and-death ordeal. At that time, apart from being unsteady on my feet, I didn't feel anything else.
