Am I Really Mentally Ill?

My name is Yan Yi, I'm nineteen years old and I just came out of a mental hospital. The medical records read: Schizophrenia, accompanied by split personality and sleepwalking. He recovered well and was discharged from the hospital. But one thing was strange - I had no recollection of ever getting sick. After I was discharged from the hospital, I began to have the same dream: at the end of the old corridor, blood seeped out of the crack in the door, and a piece of paper was stuffed out with two words written on it: "Run quickly." In the dream, someone was writing in my ear. Woke up with ink stains on my fingers. The landlord said that there was another person living in my room. But I don't know him. They said I recovered. They are lying.
