Qi Yao always thought that the monsters he saw were all his hallucinations, because those monsters could not touch him at all and did not cause any harm.
In order to avoid being thought of as a lunatic, he developed the ability to turn a blind eye to these hallucinations, until those hallucinations scratched his classmates in front of him, and his face was covered in blood.
Qi Yang: It seems that not only are there visual hallucinations, but there are also phantom smells and tactile sensations. The illness is not serious... The development of modern psychiatric drugs is really poor. How come the more I take, the more serious the illness becomes.
