Rachel was at work, so of course I was doing the dishes and cleaning the kitchen. It was around 9:00 pm, and was dark outside and inside (except in the kitchen). All of a sudden I heard a crack from the other room, like something fell. I looked around the corner, but didn't see anything. All of a sudden a heard this voice from far away say "hello". I looked around and didn't see anything or anyone. But I said, "hello", not thinking anybody was really there. But then the voice responds. It was weird.
Turns out, my phone was on vibrate. Rachel called and I didn't hear it but it vibrated off of the table. That was the crack I heard. It fell off of the table onto the hard floor. When it fell it opened up, so it answered her call. Plus, by speaker phone was on. So when she said hello it was loud enough for me to easily hear it. So it turned out to not be a ghost. That's good news.
