Welcome to the Door World

This is what a paranormal forum said: "How long does it take you to open a door?" "It takes about two or three seconds to turn the handle and push the door." "And how long does it take for you to come out of the door?" "You mean it only takes two or three seconds for me to close the door... Turn the handle again and push the door open? Your question is a bit boring." "What if the door disappears after you close it..." —— If you wake up, no, or you are stunned, a door appears in front of you, standing two or three steps away from you. Do you have the courage to open the door? Please turn the handle, push the door open, and then... Welcome to the world of doors!
