A mom has told of her terror after she heard the voice of a mysterious man whispering “Can I rip the sheets down?” on her sleep app.

Robyn Esplin says she’s “completely freaked out” after her phone captured the voice as she slept alone at her home in Cramlington, Northumberland.

She shares the property with her 8-year-old son and two dogs, ChronicleLive reports.

But the ShutEye sleeping app appears to have recorded a man with a Cockney accent making a creepy comment at 1:10 a.m. on Tuesday morning. In the same recording, Robyn’s pug, Alan, begins to bark before the clip cuts out.

Robyn said she’s been left frightened to sleep at night.

“I don’t know whether to laugh or cry,” the 28-year-old said.

“It’s totally freaked me out and I’m going to be scared to go to sleep now.

“It’s definitely a man’s voice, it’s clear as day, but there’s no one here that it could have been and I don’t know anyone with a Cockney accent.

“I’ve listened to it over and over again, trying to figure out how it’s been picked up.

“What’s getting me is that’s definitely Alan’s bark at the end of the clip so he’s heard something in order to bark. If there’s any sort of noise he’ll start yapping away, otherwise he’s sound asleep – I just can’t get my head around it.”

Robyn had only downloaded the app on Monday evening after learning about it in a Facebook ad. ShutEye, which costs more than $37.67 a month for a premium subscription, claims it records quality of sleep and any sounds during the night.

The case administrator woke before her alarm on Tuesday and checked the recording. It had captured a number of sounds, including Alan snoring, all of which were accurate.

But her interest turned to fear after she heard the voice. She has since contacted the app’s development team, but hasn’t yet received a response.

She said: “I saw the recording under ‘sleep talking’ and it took me ages to work out what it said, but now I realize what it said it’s clear as day.

Mom’s terror

“It’s only me that’s in the bedroom and I have two small dogs and my son, who was asleep in his own room. The TV wasn’t on or anything so I’m totally freaked out.”

Robyn says she locks all the doors at night, and nothing seems to have been moved inside the house. She is planning to set up a camera to help her solve the mystery.

Sun Online has contacted ShutEye for comment.

It’s not the only poor review of the app online.

One user said she called the police after hearing two men whispering in a recording at 4:45 a.m.

“You could hear one of them saying, ‘Did you put it in the bag?’ The other said, ‘Yeah’,” she said.

“I’m a single woman living alone.”

Police searched her house, and the woman complained to the app’s developers, but claims she heard nothing for three days before receiving an email to say her feedback was being passed along.
