Do you ever think your mobile phone is ringing or vibrating when it's not? That's called "phantom vibration syndrome."

你曾经听到手机铃声响起，或感到手机在振动，事后又发现没有么？这被称之为“幻觉振动综合症”。

Phantom vibration syndrome isn't really harmful -- in the study of college students, more than 90 percent said they considered phantom vibrations to be "only a little" or "not at all" bothersome.

“幻觉振动综合症”不见得有害，在针对大学生的一项调查中，超过90%的受访者认为这“仅有一点儿”或者“根本不”让自己烦恼。
