The journal mentioned a ritual that he had performed, one that involved recording the reactions of family members to certain stimuli. The goal was to capture their raw emotions on film, creating a kind of psychic snapshot.

We looked at each other, both of us feeling a bit spooked. "What was that?" I asked.

I realized that the "Cousin.mp4" video was likely part of that experiment. Our great-grandfather had been trying to tap into our subconscious, and the video was the result.

As we were laughing and reminiscing, Alex suddenly stopped the video and turned to me with a mischievous glint in his eye. "You know, I found an old video on Grandma's computer," he said. "It's labeled 'Cousin.mp4'. I haven't watched it yet, but I'm guessing it's something from when we were kids."

Alex shook his head. "I have no idea, but I think we need to find out."

Alex shrugged. "No idea, but I'm willing to find out."

My curiosity was piqued. "What do you think it is?" I asked.
