Horror details have emerged after a man claimed to have had a UFO encounter after seeing what he called "tentacle-like lights" in the sky.

Richard Powers of Bacliff, Texas said he saw the unexplained beams of white lights coming at a phenomenal speed while at a gathering at his home with friends on October 4.

Powers told Galveston County's Daily News that he first became aware something unknown was in the sky when he looked up and noticed a bright orange flash, from which thin lights emerged, and then separated rapidly into eight different beams.

“They were so fast it was phenomenal," he said of what he believed to be UFOs.

“If you blinked you would’ve missed them.”

The beams continued to travel through the sky, Powers said.
