It was a cold evening and Robbie was getting ready to go out with his mates. When getting changed, he noticed an interdimensional portal inside his closet. Curious, he walked into it and ended up in Ainran! It was a backwards society, literally. People wore gloves on their feet and shoes on their hands. Shop keepers payed their customers to get their goods. Gravity even worked in a weird way as houses were upside down and swimming pools were sort of floating. Birds chased cats, who chased dogs, who chased humans. Oh wait, dogs already chase humans. Anyway, this was all too much for Robbie, so he left the strange world of Ainran and went clubbing with his mates. One hangover later, he forgot the events that led him to Ainran and dismissed it as a dream.
THE END!
