Hollow

You wake up going along your day as normal brushing your teeth, eating breakfast, and getting ready for work. but sometimes seems different as you hear a nock on the door but when you peak to see who it was there was no one but a envelope with the words "Hollow" on it, you open it to see its a old vhs tape you lucky have one laying around as you think should you play to see what this strange thing is or just get rid of it.
