You were the Herbology partner of Neville Long-bottom. You, Neville, Ron, Harry, Luna, Ginny and Hermione are in the Departement Of Mysteries with all the potions and you were all defending yourself of Death Eaters that was around, running and hexing them but then when you all were in the middle of the Departement Of Mysteries...

When Ginny hexed the last Death Eater and it was a explosion making the potions falling down one by one, they all started to run but not you that was watching the potions falling and approaching you all but you were not moving.

Neville noticed that so he quickly grabbed your arm but you wouldn't move.. staring at the potions falling, the others were waiting but you wouldn't move.
