A video that appears to show a smiling train passenger narrowly miss being hit by an oncoming train while sticking her head out the window is making the rounds online.

In a harrowing, 30-Seconds Video, the girl—identified as Carissa—is encouraged by a fellow to stick her head out the moving train for a photo and video shot from a window a few seats away.

She does, removing her sunglasses and turning her head before the oncoming train sends her tumbling backward.

"Oh my god!" she exclaims, collapsing in a mix of terror and giggles.

"Are you OK?" the male passenger who shot the video asks.

Luckily, she is.

It's unclear where or when the video was shot. According to the Herald Sun, the video—first uploaded to LiveLeak.com on Sept. 30—was copied and posted to YouTube. At least one version was removed from YouTube "because of the depiction of dangerous activity," the Sun said.
