Don't pee your pants

You are in your house, you look outside your window and think "What a beautiful day, but what if we are in a simulation, and that simulator is inside another simulation. and THAT simulation is in a simulation that's inside another one and repeat forever. What if we create robots then the robot takes over the robot then the ROBOT takes over the world. And stuff" Then you see a plane crashing into a building, 9/11.
