The effects weren't limited to Yi Chen alone,
Lene, who was also in the hotel, underwent a similar brain inspection in her dream, though the 'damage' wasn't as severe as Yi Chen's. She merely visited a mental hospital where a nurse personally inserted a syringe into the back of her head and quickly extracted part of her brain matter.
According to Lene's account, after the extraction, she enjoyed a lavish post-operative meal in the mental hospital and was then placed in a clean ward to sleep. Upon waking again, she returned to the hotel.
Thus,
it seems the intensity of the inspection at the Lighthouse Mental Hospital might be related to the individual's 'conscious resistance'.
After both of them were inspected without any follow-up actions, it suggests that the mission involving the circus has been successfully concealed.

"Thank you, boss! Thank you, boss!"
On a high building, on a floor transcending the world's limits.
