Woman escapes terrifying encounter with man who claims to be 'half alien'

Mary Kate Heys is only 20 years old, but she has lived through a real-life horror movie.

The British woman went on a backpacking trip through Australia in early December, and what started as a pleasant adventure turned into a horrifying affair.

On her journey through the country, Heys found herself at the hands of a man who called himself "half alien, half human," according to NBC News.

When she met the Swedish 22 year old, he seemed pretty normal. The backpacking friends became close after a few weeks together.

According to the Daily Mail, their casual relationship took a strange turn when he asked her an odd question: "Do you want to go on the adventure of your lifetime?"

She told NBC News the man had "psychotic eyes," but nonetheless, she decided to go on a trip with him.

They agreed on a short drive to Brisbane, but he suddenly changed his mind and decided they would go to Cairns, which is an 18-hour drive away.

While on the trip, Heys told NBC News he dropped a horrifying bomb.

"And he said, 'I'm gonna say something that might alarm you. But I'm gonna say it in the best way I can.' He said, 'I'm half alien, half human," she said.

Heys added that he spoke with such passion, she "actually kind of believed him."

Just when she thought it couldn't get any weirder, he told her that she is an extraterrestrial as well.

"You're the one, you're the same as me, you're the one I've been looking for," he said, according to Heys' interview with NBC News.

"And he said 'grab my hand.' So I grabbed his hand... And he said, 'Can you feel it?' I was like, 'no.' And he said you'll feel a warmth, soon you'll feel a switch come on inside you and you'll be exactly the same as me."

She told NBC News that at this point, the man was so erratic, she thought he was going to kill them both.

Since he would not let her leave the vehicle, Heys did what many people do when they are terrified -- she texted her dad.

Her father was able to share her location with Australian police, and after two and a half more hours, police caught up and forced the car to pull over.

"I just leapt out of the car and ran over to the police and I couldn't let him go of the policeman like I was in some weird shock," Heys told NBC News.

"I was crying and shaking."
