"Flashbacks" and nightmares

The balance of the universe is restored, as today a student informed me that they were having "flashbacks" to my course last semester. The word "nightmare" was used more than once.

Me: "Well, I hope you used your experience to warn future students away from my class!"

Student (chuckling): "No, I told them all to take it! It was really good."

I'm not sure if it's Stockholm syndrome, sheer sadism, or a third option, but I'm glad to see that my veneer of frighteningly demanding professorhood has been restored. (See a few weeks ago, when a student called me "benevolent".)

(On a more serious note, I am now awash in guilt and concern over the negative impact that my job has on student mental health.)

This post's theme word vituperate, "to use harsh or abusive language." In manner and outward appearance mild and approachable, she nevertheless invoked the same fear as if relentlessly vituperating her students.
