Weird Invasion: Beginning with a Nightmare

(Weird + infinite flow + wits to survive + no high combat power) They all forgot. Forget that people who die in dreams will completely disappear in reality. Only I remember. So, I was left behind, marked with a "mark", and became the prey that the strange world constantly hunted. When the psychiatrist determined that I was schizophrenic, and when my best friend looked at me with pity, I knew that the next time I closed my eyes, I might never wake up again. And now, the mark is starting to get hot... They are here again.
