[@Damiann47] By the time the ghost hit you Bulwark was already active. I'm not sure how large you imagined apartment to be, but between Sonia and the ghost when it spawned were some 4-5 meters and it was already moving when Sonia decided to close her eyes to calm down. I am aware she would've opened them once the technique is activated and she did, the thing is that once she opened again the ghost wasn't in front of her anymore.
