虚梦

Translating directly, 'Xu Meng' gives 'empty/vain dream' which signifies illusory or unrealistic desires. Dreaming is a common theme for online handles; here, however, there’s a particular focus on unfulfilled fantasies – daydreams without substantial basis or outcome in reality, highlighting perhaps pessimism, sarcasm, or just wistfulness about wishes unlikely to come true. Also symbolizing how life sometimes seems elusive and transient.
