CAUGHT ON CAMERA!!! SOMEONE EXPLAIN...

Normal night playing the PlayStation upstairs while my roommates dog downstairs starts barking like an intruder is in the house. I go downstairs and see no one. My roommate has been gone for hours so I figured the dog needed to use the restroom outside. I grab her leash and she runs away from me which is odd because she loves getting fresh air no matter if she needs pee or not. I close the basement door and walk in the room to see her huddled up on the couch shaking with her toy in her mouth like a child would have his or her teddy bear to keep them comfort. She didn't need to go outside and she didn't wanna play. The bark was a intruder type. I sat down next to her petting her while pulling up my security camera on my phone and what I saw had me feeling every emotion from excited curious confused creeped out and more, Minus the Fear because I have strong faith in my Creator and this is my home and I've prayed and have protection around me and my family in this house. No weapon formed against us can prosper in Jesus name, amen. 🙏
