A strange blue cloud seen floating and darting around customers, freezing for 30 minutes and then speeding from an Ohio gas station, remains unexplained even though it was caught on security cams.

The ghostly image was seen moving near and over cars at a Marathon gas station located near the corner of State Road and Pleasant Valley in Parma on Sunday.

Surveillance video of the image showed it flipping and then sitting in the same location for 30 minutes.

It then flies off the screen at a high rate of speed.

"It gives me the chills," a witness said.

Security video then shows it coming back and resting on a car window before floating away.

Several people said they believe the image is a ghost or an angel.

"It was an angel," a witness said. "There was an angel here."

The owner of the gas station said he was happy the image went away and has not come back.

"I actually watched it for 30 minutes and then actually I watched it move and that is when I got freaked out," said owner Amed Abudaaria.

Groups of people have traveled to the gas station after word spread of the unexplained event.

None of the people getting gas seemed to look at it.
