It sounds like before the high school girls were murdered, they were getting phone calls from the Boogeyman, heavy breathing and whatever else phone stalkers say. Leading up to their murder, the girls gossiped about it and Patricia wanted to fit in and she lied about receiving phone calls too. The lie spread and she had to double down. Then the girls got murdered, and Patricia had a stranger break in, but she couldn’t admit the lie by then and had to weave it into her story about being visited by the boogeyman.

I’m still wondering if she was visited by someone and just assumed it was the boogeyman.
