Talk to me「I don't know anything.」(5)

"Although I may agree with you by 50%, I may not agree with you, but I want to remind you that the topic between us seems to be too far away. Let's go back to the topic of "mental patients" and "mental diseases"!"
"Okay, can I ask you another question?"
"Of course, you ask."
"Do you dream?"
"Of course."
"Then do you have nightmares?"
"Do it!"

"Have you ever been scared by your nightmare?"
"Yes, but that only happens occasionally!"
"The ancients said, "Thinking every day and dreaming at night". Do you think the ancients are right?"
"No, nightmares come from my fear of the unknown. If it is really the dream of "thinking every day and dreaming at night", I don't think it must be a nightmare."
"Then what are you thinking during the day?"
