Here are some ways to translate it into English:
* Possessed by a demon/devil - This is the most direct translation, emphasizing the idea of being controlled by something outside of oneself.
* Be blinded by/lose one's mind - This emphasizes the aspect of losing reason and judgment.
* Be completely out of one's mind/be in a daze - This emphasizes the state of being disoriented and lacking clarity.
* Act irrationally/make a foolish decision - This highlights the behavioral outcome of being "鬼迷心窍."
The best translation depends on the context and the intended nuance.
For example, if someone is making a reckless decision, you might say they are "blinded by their emotions" or "acting irrationally." If someone is behaving in a way that is completely out of character, you might say they are "possessed by a demon" or "completely out of their mind."
Ultimately, the translation should capture the sense of being irrational, misguided, and lacking control over one's actions.
