Draco was looking over at her with anxious eyes and she could see he was mouthing to her "you’ll be okay’. Just seeing that he was talking to her as if he knew her was enough to confirm that those times together months ago was not all fabricated in her head. She started to ease a little and think a bit more pragmatically, maybe there was a reason for this. The hat had specifically told her to trust it before, and she did and look how that turned out, maybe she just had to trust it again and it would lead her onto the right path again.
