干嘛那么贪睡阿因为梦里有你呀
[gān ma nèi me tān shuì ā yīn wéi mèng lĭ yŏu nĭ yā]
This translates to 'Why am I so sleepy? Because you are in my dreams.' It playfully expresses a longing or infatuation, suggesting that the individual misses someone so much that their thoughts and even their subconscious revolve around them, causing a desire for sleep to be with them at least in dreams.
