Facetime ringing in early morning on computer

Lately over the past week or so, my MacBook Pro has been ringing like a phone call coming in early in the morning (5am or so). My very understanding roommate just closed the lid to my laptop which worked, or he turned off the computer. Either way it stopped. I like putting my screen up, so I can run backups and such overnight. Anyone else having this issue? I’m a little perplexed.

There are no reminders due or missed phonecalls in the facetime log?
(could be a repeating reminder?)

If you have power nap on your backups will happen with the lid closed.
