Phantom vibration syndrome

Phantom vibration syndrome or phantom ringing is the perception that one's mobile phone is vibrating or ringing when it is not. Other terms for this concept include ringxiety (a portmanteau of ring and anxiety) and fauxcellarm (a play on "false alarm"). According to Dr. Michael Rothberg, the term is not technically a syndrome, but is better characterised as a tactile hallucination since the brain perceives a sensation that is not present.
