The sensation that your phone is vibrating in your pocket when it is doing nothing of the sort is not unique.
Philosopher and assistant professor at Georgia Institute of Technology, Dr Robert Rosenberger describes the feeling as a "hallucination" caused by anxiety, and says it is quite common.
Dr Rosenberger studies the effect technology has on our lives and thinks the phenomenon is a result of always being "on-edge" to answer emails and text messages.
