GETTYSBURG, Pa. (WHP) – A video posted by a tourist that shows what appears to be a ghost sighting at a Gettysburg battle field has launched an online debate.

A story written by the New York Post states that New Jersey resident Greg Yuelling took the video while on a trip to Gettysburg with his family on Sept. 2.

The clip captured by Yuelling appears to show ghostly figures walking around tow cannons on the battlefield.

Although the sighting was captured on camera, some people aren’t convinced.

The reason most people are seeing a “ghost” is because they already know about the history of Gettysburg, and our brains will automatically try to make something familiar out of a visual anomaly,” the organization said in the post. “The entities are actually just the light being distorted by the streak on the windshield as the background elements move into the streak.”
