Psychologically: Whether one dreams of jingling on coins or of trying similar on piano keys - it is always a symbolic action for something that one does to attract attention (or to deflect himself) although 'the suitable means are slightly'. (Typical statement of an attempt to make advertisement for a little bit or somebody: 'Jingle heard to the craft!') If a woman jingles 'on the eyelashes', it is also a signal gesture which should cover up as a little (real feeling) lies behind.
