CALGARY, Alberta -- Some believe aliens have landed in western Canada after seeing strange reflections appear almost nightly on the wall of a Calgary home.

"I looked out and I thought, 'Oh my gosh, I've lost my mind,'" resident Karen Henuset said of the first time she saw the specters. "So I asked our nanny to come and take a look at this, and the hair on her arms just stood straight up."

It's as "clear as day. You see two eyes on each of them, they both have this little thing over their head. It's a little weird," said resident Reid Henuset.

A neighbor said he believes the image is a reflection off of a window. And it only happens every afternoon between 4:30 p.m. and 6 p.m.

The only sure way the image goes away -- clouds.

Although some adults may be skeptics, ask the neighborhood kids what they think and the answer is unanimous.

"There's aliens, real-life aliens on a wall," one unidentified girl said. "No one believes us."
