To me it is so many things.... Solitude, in a world all ur own. Imagination, everything can be nonsense. Choices, they can sometimes make us grow stronger. Literacy, 読書 本 without pictures can create beautiful 画像 in our mind.
To me, Wonderland is a place. A place where rules can be broken and new, crazy フレンズ can be made. It's a place where magic and imagination clash in a burst of color and weirdness. It's where ネコ and rabbits and lizards can talk and stand on their heads, and where あなた play クロッケー, クロケット with flamingos and hedgehogs. It's where 妖精 and sprites become life sized beautiful and handsome creatures.
