"When was the last time you thought about sanity? A year ago? Today? Never?
Some people think about it every day. Waking up in the middle of the night, he hears strange noises.
Brushing his teeth, he notices something in the mirror. Eating breakfast, he tastes nothing but spoiled food.
Are you sure this is reality?
Have you lost your mind?
Do you have all the answers?
Maybe today you will finally figure out the truth."
