If somebody knows your weak spots better than you do, they’ve got a key to a door you’ve never checked.

Someone else can study you more attentively than you have, especially if they have a reason to. They notice which comment lands, what you need to hear, where the hesitation is. None of that is dangerous in itself. It becomes dangerous when the map they hold is more detailed than the one you hold.

Spend some time on the parts of yourself you tend to look away from. What you are anxious about, what flattery works on you, what you will do to avoid conflict. Knowing them yourself is what closes the gap.
