I always have a lot of weird dreams. I get bitten on the head by a dog, my teeth fall out, I get shot in the shoulder and don't feel any physical pain, and goldfish float in the air... But the most frequent dream is about the door to my house that won't close no matter what. Nightmares reflect people's state of mind, and I combined the illustrations with mirror paper to make a three-dimensional handmade book that can rotate. When the mirror book rotates, it also means that I can't close that door in my dreams and I can't escape even if I want to. I try to connect the fear in the dream world with the real world, so that the viewer can experience the intricacies between the dream world and the reality while rotating the mirrored book. Doors that cannot be closed may represent the difficulties and challenges we encounter in real life, while the inability to shout or move may reflect a mental state where we feel bound or helpless.
