In the video below, you will see something move and seem to disappear on Elizabeth's arm. She obviously feels something because she moves her arm at the moment the object disappears. We aren't really sure what it is, although I can't rule out the possibility of it being a bug, even though I don't remember seeing any that night.
The clips below have been unaltered from the original recording. It may be necessary to listen to these with headphones on, as some of them are very faint.
In this clip, you can hear the word "Hello"
This almost sounds like a large bell on a door or glass clinking together
Donna had stepped outside to see how hard the wind was blowing. She was by herself, but it sounds as if someone says "What are you doing?"
In this video, the first object you see on the left side of the screen is a piece of lint or hair floating downward. After you see that, focus on the center of the screen and you will see something move up and then to the right, straight towards Elizabeth. Not sure what it was about Elizabeth that night, but she seemed to be attracting something. Once again, I can't completely rule out the possibility of it being a bug.......but it sure doesn't look like one to me.
