Cách sử dụng
The expression "like a bad dream" is used to describe a situation that is really unpleasant or difficult, and feels like it's not real - almost as if you were in a nightmare. For example, if someone is going through a really tough time because of a problem they can't solve, they might say "it's like a bad dream - I can't believe this is happening to me." It's used to convey a sense of shock or disbelief at the situation.
