Another short doujinshi from Giselle (

...translator's note time! ^o^
From wikipedia:
Once Zhuangzi dreamt he was a butterfly, a butterfly flitting and fluttering around, happy with himself and doing as he pleased. He didn't know he was Zhuangzi. Suddenly he woke up and there he was, solid and unmistakable Zhuangzi. But he didn't know if he was Zhuangzi who had dreamt he was a butterfly, or a butterfly dreaming he was Zhuangzi. Between Zhuangzi and a butterfly there must be some distinction! This is called the Transformation of Things. (2, tr. Burton Watson 1968:49)
...and this would be the original 'butterfly dream'! ^^
The things one learns when translating Japanese doujinshi about anime couples, eh? ^__^ My philosophy teacher would be so proud!
...or not, given I had completely forgotten about this and had to look it up in Wikipedia... *cough*
