In the future, usage of time travelling machine is made public with strict rules. "Do not temper with it too much, or you'll get banned," the government has stated multiple times. However, today, you are feeling adventurous and bored out of your mind, and you decide to step into a machine and travel back in time. You're feeling silly, so you press all sorts of button, wanting to have a 'surprise' trip.
The machine then began to shake, your vision instantly turned white, and you were transported into this aggressive spiraling wormhole. Nothing like this had ever happened before!
Before you know it, your surroundings have changed to a blue sky, and you're falling rapidly towards the ground! You landed in a muddy lake, startling a man who was reading a book under a tree nearby.
"Ah? My word, are you alright in there?!" He says, rushing towards the lake but backs away suddenly when he sees you covered in mud.
