Jenny, who lived alone in her second-story apartment, had heard the odd clicking sounds before and was accustomed to having the inexplicable midnight noises jar her awake in the middle of the night. In an attempt to help her analyze her sleep patterns and discover the source of the odd sounds, she installed an app on her phone, Sleep as Android, a sleep improvement app, available in the Google Play store, which includes an alarm, soothing sounds, and a “sleep talk recorder” that records snoring, sleep talk, cover ruffles, coughing, and other nightly sounds.
Sleep app recording reveals ghostly voice speaking to woman in middle of night
Jenny began using the app on October 1, 2013, and at first, only heard sounds of her coughing, moving, or adjusting the bedcovers. But on December 30, 2013, the recording revealed something terrifyingly unusual. She noticed the recording as she was deleting old tracks and saw curious audio patterns on a track recorded on the night of December 30. According to Jenny in a post on the popular Reddit forum:
“In it, you can hear some clicks that start to get louder over the course of the recording. Eventually you can hear me say “What are you doing?” and immediately after there is a deep voice that says “Nothing”. The clicks become very loud at that point and at the very end of the recording you hear the same voice say, “I’m dead”.
Jenny was frightened, to say the least. She asked readers for assistance in solving the mystery.
“I would LOVE some debunking here. I like creepy stuff but certainly NOT in my own home.”
Was the second voice Jenny talking in her sleep?
The most obvious theory would be Jenny talking to herself in her sleep. However, this was easily disproved. Jenny voluntarily allowed an investigator to analyze her voice for comparison to the audio recording. She sent the investigator ten samples of her voice recorded at different volumes and various cadences. The audio analysts concluded that there were two separate voices on the recording – the second voice being that of a man.
“The other person in the recording definitely isn’t you talking to yourself. Your voice’s pitch in the question “what are you doing?” is around 265Hz (C4 in musical notes) and the answerer’s voice seems to be around 90Hz (F#2). That is relatively low voice for even a man.”
Later the analyst reported a more detailed account of his findings. He provided a spectrogram of the recording and noted:
“I noticed there’s a visible peak also in the 90Hz area of the spectrogram. It’s not very loud… Maybe because the person was a bit further away from the mic and the man was speaking rather quietly? Maybe the microphone (or the app) couldn’t catch the lowest frequencies very well? That’s often the case with low-end recorders like this.
It’s possible to prove that the speaker’s pitch is indeed 90Hz. The human voice is composed of multiple different “overtones”, or “harmonic partials”. Basically, what it means is that when you speak, there’s a base frequency (pitch) in your voice, and then over that there’s tens of other higher frequencies overlaid. Those overtones are what make your voice sound like you.
In normal human voice the overtones always appear in the same intervals going upwards from the base tone: Base – 1st octave – fifth – 2nd octave – major third – minor third – minor third – 3rd octave – etc. When you look at this spectrogram again, you can see that the 190Hz tone is the second harmonic partial, because the next one above that is a fifth upwards, not a full octave. That means the base tone has to be the faint 90Hz (F#2) visible below the 190Hz, because it’s exactly a full octave lower.
This means that the other person in the recording cannot be the woman, as no ordinary woman is capable of producing an F#2 with their vocal cords.”
An intruder in her home?
The second theory, one that is equally as scary, is that an intruder entered her home and answered Jenny after she spoke in her sleep. The clicking sounds could have been the sounds of a burglar rummaging through her belongings. However, nothing was taken from her home that night and nothing appeared to have been disturbed.
“The radio was untouched, belongings were untouched, no broken windows to suggest forced entry.”
“It was pretty traumatizing for me”
Two years later, Jenny still has no explanation for the ghostly voice recorded in her bedroom in the middle of the night. She told forum readers:
“It was pretty traumatizing for me. I don’t think I will ever know what the hell happened that night, but I am now 100% certain that the voice was not mine.”
Jenny has since moved from the home (to a “less creepy place”). At her new residence, she continues to record her nightly sleep patterns but to date, has captured no more unexplained voices in her recordings.
Check out the recording below. I’ve cleaned up some of the noise and adjusted the volume in order to make the clicking and voices easier to hear.
