Hackers or Ghost?

Early this morning, 3am, I got woken up by the bachelor playing over my laptop in another room. After about 15 minutes of brainstorming what it could be or if it’ll stop on it’s own I got up to stop it. There wasn’t a ghost nor was there my housemate drunk and high watching some late night reality TV, my laptop was closed and when I opened it and unlocked it it was playing. I don’t even know how to play media with it in sleep mode, plus I closed it around 10pm Should I be looking into some computer security or is it a normal little thing to happen?
