Imagine, you woke up in a white room with dropper and some wires, connected to your body. You don't understand, where are you and how did you get there. You see only a bed, dropper and device standing in front of you, door, and a speaker on the wall.
In a few second you hear : "So, did you like the simulation, was it fun?".
What would you do and say? How do you think you'd act?

I personally think i'm going to "I don't believe that shit" first, and then i'll lose sanity when i'll realise that's true
