A SEATTLE couple was left spooked when they returned to their apartment to find it trashed in mysterious ways — but nothing missing.

When Brian and Bridget O’Niell came home on Wednesday, they found lotion smeared all over their doorknobs, their junk mail torn open, and a can of paint overturned in their toilet, according to Vocativ.

Bridget O’Niell’s clothes were also strewn all over, and the couple’s electronics had been piled high on top of their bed. Strangest of all, the soles of their shoes and boots had all been removed.

When police came to investigate, they were confused to discover nothing had been stolen. However, they did find a purse belonging to a 27-year-old woman.

“We didn’t feel threatened, but we were somewhat disturbed,” Brian O’Niell said. “It was a really weird experience.”

It wasn’t until the couple started cleaning the mess that the chilling truth came out.

Brian O’Niell moved the bed slightly and something stirred underneath. “It was a noise coming from something alive,” he said. “It sounded like a dying possum or raccoon.”

When the noise became louder — along with the sound of fierce scratching — they couple fled the apartment and called the police again.

Officers went inside and emerged minutes later with a gangly, wild-eyed woman who had apparently spent the last two hours hiding under the bed.

“When I saw that it was a woman, my reality suddenly kind of shifted,” Brian O’Neill said. “My wife pretty much collapsed on the stairwell.”

The woman — standing at about 170cm, and weighing an estimated 40kg — reportedly told authorities she had been on a “meth rampage” for several days.

Even more terrifying, the couple later discovered a hypodermic needle in their sheets and a large kitchen knife under the bed.

“Rather than use the knife to pop out and murder us, she was using the knife to deconstruct the box springs of the bed,” Bridget O’Neill said. “Honestly, I feel kind of bad for her. This woman was so tiny and not together, it’s hard to be mad.

“If you describe yourself as being on a meth rampage, you’re probably in bad shape. I feel like regular old meth is bad enough.”
