creepypasta-Open powershell window here part 1

I was in informatics classes  MR.Gordon was giving the instructions while literally he was playing FORTNITE, everything was awsome until he said: -"shift, right click and select open powershell window here"- i followed the instruction but just when powershell window opened my pencil fell to the floor, and when i looked back to the screen the messege "you opened me i will pen you"I thought that everything was a joke, but when i tried to tell the teacher  i could'nt say something in that moment, not beacause the teacher doesn't wanted to listen beacuse he desapeared. I was very scared not just beacause the teacher was not there every single person in the school (I think) desapeared in that moment. But in that moment i said: "how will a computer open me?" my question was answered very quickly...
