Stevie takes notes and takes pictures of this person which shows is paranoia as it is just a regularly normal person walking past his house.
The hoodies create the representation that they just loiter. They cause disturbance for Steve as they play music quite loud which affects Steve and causes him to break down. Some of the hoodies then come back later and break in and Stevie feels like that people are out to get him.
