I am always in a daze when others are talking. .

This means that you are distracted! Pay attention to why you are distracted in this respect, whether you have something to do well or something urgent.

Or the other person is saying something that makes you feel bored, so you start to be in a daze. Or they are saying something that has nothing to do with you, making you feel that you have nothing to do and just stay there in a daze.

However, sometimes this kind of behavior is extremely impolite, and the speaker will think you are disrespectful. But it's best to find out the root of the matter and cure it.
