[HELP] Weird Notification

Hi everyone, a notification just popped up in the notification center and I have no idea what it means. I opened the laptop and it was the first thing that popped up but I'm not sure if it's related. I'm at 100% charge right now and the laptop has been plugged in all day. This is first time I've ever seen something like this and when I google and can't find anything, it worries me.

Any clues?

Do Not Sleep

Also attaching a pic of it. Thanks in advance.

 

Ah, you're right on! I totally forgot I even had parallels running. Thank you so much good sir!
