Veteran of the Pillow Wars

You are a resident of the Гильберт отель (Gil'bert Otel'), prestigious and limitless hotel beyond reality, connecting all worlds and dimensions. For exactly one eternity you have been quarreling with an infinity of other residents, knocking on walls, complaining to the front desk about the cacophony hoping to finally get some well deserved sleep. One day you got fed up, and you jumped through the tiny window of your room. You have been falling since, whirling rapidly in and out an infinity of world. Your true form is unfathomable to the inhabitants of the lower dimensions who see you as a tired middle age travelling salesman in pajamas, with bags under his eyes.
