Tales of bright lights over marshes

In one of these tales, which was in a book written by Wirt Sikes, a man was traveling home in the dark and as he was walking, he saw a bright light a bit far off and he decided to follow it for a few miles.

He saw that the light was coming from a lantern that was held by a shadowy figure, and after following it for quite a distance, he found himself standing on the edge of a gorge with water violently rushing just below him.

All of a sudden, the shadowy figure appeared beside him, carrying the lantern, and then laughed evilly before blowing out the light of the lantern, and then leaving the man all by himself on the edge very far away from his home.

In other tales, the Will o Wisp has been related to spirits of people that were not allowed to enter Heaven or Hell, and are now forced to live on Earth, leading foolish travellers astray.

The gas is believed to ignite on its own and form those flames that are believed to be the Will o’ the Wisp.

Science has also purported the possibility of these sightings being a result of ball lightning.
