Eric: “What happened last night? You woke up SCREAMING in the middle of the night, it was crazy.”
Emily: “I know, sorry. I was having this really horrible nightmare.”
Eric: “What happened?”
Emily: “I was in a classroom trying to get everyone to be quiet and no one was listening, and no matter what I did, the kids kept misbehaving, and totally ignoring me like I didn’t even exist, so finally I mustered all my strength and just yelled as loud as I could.”

So basically my “really horrible nightmare” was my regular life every day for 9 years.
