There are many things that could be called 'Suburban Screams'.

Most likely not true stories. Suburban Screams is likely a product of imagination and creative writing. It could incorporate themes and tropes that are familiar, but that doesn't mean it's based on actual events. The purpose is to entertain and captivate the readers/viewers.
