Circles on the field and other formations. Spain

A worker was alone at a local water plant when suddenly all electricity and light at the plant was shut off. He went outside to see what had caused the outage and felt a strange electrical sensation in the air. He then saw about 200 meters away a hovering luminous object that was very close to the ground, it was shaped like a half egg on top of a plate, and it emitted a brilliant orange green & purple light. Next to the object stood two tall human like figures wearing shiny silvery orange outfits, one of the beings bent down under the object and appeared to look inside. All the time the witness was not able to move a muscle, holding a flashlight in his hand. Somehow he was suddenly able to turn the flashlight on and both beings re-entered the object, which then ascended slowly emitting a loud buzzing sound and increasing in luminosity. Ground traces were found at the site. And the witness almost suffered a nervous breakdown afterwards.
