The cause of so-called phantom ringing syndrome the feeling of your phone ringing or buzzing away in your pocket has been discovered by researchers.
Alex Blaszczynski, chairman of the School of Psychology at the University of Sydney, believes the sensation is actually triggered by electrical activity.
"I expect it's related to some of the electrical signals coming through in a transmission, touching on the surrounding nerves, giving a feeling of a vibration," the Daily Mail quoted him as telling the Sydney Morning Herald.
Although Blaszczynski hasn't conducted any formal studies on the vibrations yet, if he is right then the feeling isn't a figment of our imaginations, but a real sensation.
However Larry Rosen, a professor of psychology at California State University disagrees.
He believes that because people are often anticipating a call they often interpret unrelated stimuli, such as a chair leg dragging against the floor or trousers rubbing their leg as a phone call.
And Michael Rothberg, a clinician investigator at Baystate Medical Center in Springfield, Massachusetts, who conducted a survey on the vibrations, agrees that they may be caused by the misinterpretation of sensory signals in our brain.
Rothberg's study found the phantom phone vibrations were experienced by 68 percent of people surveyed, with 87 percent feeling them weekly, and 13 percent daily.
"In order to deal with an overwhelming amount of sensory input the brain applies filters or schema based on what it expects to find, a process known as hypothesis guided search," he said.
