He just opened his eyes, there's an incredible noise. When no one else hears it, you feel like you're going crazy, said Simon Payne, 55, of Cambridgeshire. Payne is one of many other people who have heard the global phenomenon known as Hum.

I changed my house so I wouldn't listen to him anymore,” he added.

Hum experiences as a growing low-consistent noise, similar to that of a large truck driving in a nearby parking lot. Listeners of this noise have said they've heard it in urban areas, making some people think it's actually the form of noise pollution.

The symptoms are said to be sleepless, headaches, and dizziness. But other symptoms may be the source of the noise still unknown.

Some previous reliable reports of the UK phenomenon date back to the '70s.

Such noises were heard in Pristina years ago.
