Day 3
We checked the footage this morning, and it's much freakier than I thought. While we were sleeping, you can hear loud booming slow footsteps coming up the stairs. Then suddenly the (Chihuahua) dog appears in our doorway, just standing there. It doesn't even move. Its silhouette is black against the soft yellow light from downstairs. It didn't even get to the doorway. It just suddenly appeared there. Then the door slammed shut, in its face. Really hard. The dog didn't even touch it, it just went bang! and slammed shut. We woke up with a fright and opened the door. The dog was gone. We went downstairs and found it clinging to the chandelier.
It still is.
