Christopher Hogg spotted hundreds of sheep stand in a circle formation in a field in East Sussex, England.
The bizarre scenario has since been posted on Facebook, eventually going viral.
“I was on my daily cycle and came over the hill and saw this magnificent circle,” Chris said.
According to Hogg, the sheep are usually noisy, but they were calm and still that day.
Hogg feared that he had encountered a flock of sheep that were under the control of a “foreign being” or “aliens”.
“It was so quiet, like they were in a trance. It was very eerie,” he added.
