App triggers REAL nightmares on demand.

If you could, would you choose to have horrific nightmares? Apparently, there's an app for that.

The UK's cult horror station Horror Channel claims to be "dedicated to the dark side of cinema and television", but now they're branching out into something much more personal - your dreams. Their iOS app Night Terror is designed specifically to induce very real and totally terrifying nightmares, on demand.

After installing the app, you select one of a number of audio stories to listen to while you fall asleep. You're instructed to lay your device next to your pillow, so the app can monitor your movements to track your sleep progress. Once you're in the suggestible REM sleep phase it'll subject you to a series of sounds, all designed to interfere with your subconscious mind, steadily steering you away from the happy thoughts and leading you down the dark deserted roads of horror.

At the top of their app site they have a large disclaimer instructing the seekers of scares to think twice before giving their app a shot, it says:

"Warning: this application is designed to interfere with normal sleeping patterns and may cause real nightmares. It is not suitable for anyone of a nervous disposition, anyone who has suffered a traumatic event, night terrors or any sleep oriented distress. Consider the immediate and long-term effects of evoking and enduring a nightmare very carefully before using this application. Strictly over 18's only."

Despite the warning it sounds like one "hell" of an experience. So, will you be trading your sweet dreams in for subconscious scares?
