I think I might’ve been visited by something…

First-time poster here, but something really strange happened at my home this morning before I woke up and it is bothering me.

Around 3 am, my dog woke both me and my mother up to the noise of him chewing off his diaper. Mom wakes me up after she is up herself, and is visibly spooked, and asks me if I turned on the gas logs last night.

I didn’t, and even stranger the metal door that covers the knobs is open and the flames are running high.

But that’s easy enough to contribute to one of us forgetting we turned them on right?

I wish that was the only thing. In my mother’s room next to her side of the bed is a perfect ring of blood with a 2ft diameter that looks fresh.

Obviously, we were very confused and checked to see if my dog had bled any during the night, but didn’t see anything.
