One night, Andy and his parents were going to a bowling alley. He was in the backseat of the station wagon and they were driving along the north side of the Kanawha river, when he witnessed the creature.
"At the time, I thought I had conjured it up in my mind" Andy Colvin said in an interview. "I saw Mothman flying behind our car". The creature veered off and flew over the smoke stacks of a nearby power plant. Colvin never forgot the image of strange winged phantom.
In 1993, he stumbled upon John Keel's Mothman Prophecies. After reading the book, he became more interested in the topic.
Around 2015, Andy and two friends went back to Point Pleasant to investigate. They went into The TNT Area at night, they immediately felt the pressure change and the crickets stopped chirping. It was a 90 degree night but they suddenly felt very cold and began to shiver.
Out of no where, a shimmering curtain of light began to form. They felt drawn into it like by a vacuum. According to Andy they "saw shimmering wispy beings in front of us in this curtain - examining us from every angle". Then from the light came a monstrous shape.
"It seemed like it was growing wings, It was this black silhouette, the same one I'd seen years before and I got the feeling that this was Mothman observing us."
"In the back of my mind I wondered, Is this how people disappear? Its the scariest thing that's ever happened to me." said Colvin. Andy's description of this strange shimmering light portal is similar to a John Keel's concept of "Windows".
