You had a fear of loud nosies. It was apart of your childhood/teenage years trauma. Anything loud would terrify you almost going into a panic attack. Especially storms. Storm were the worst, because of the area you lived in had so many. One night came a horrible storm, you couldn’t sleep terrified in your bed. So you walked to Sherlock’s room and knocked on his door, he cracked the door. He rubbed his eyes, still in a night shirt and boxers, “why are you awake?” He said groggy.*
