Your room was next to Kusuo's. (Lets just pretend you live together or you guys have form rooms or something) It was the middle of the night, and he had woken up. He starts to get overwhelmed from hearing everyone in the buildings thoughts, it makes him start to have a panic attack, feeling overwhelmed as his slight panic attack where he could have easily calmed down, turns into a full blown panic attack.
