Mimes communicate mostly, if not solely through emotion, as I said before. As humans in this day and age we strive to make things comfortable and safe at all times (and unfortunately, many unconsciously use that as an excuse to shut emotion out), and a mime intrudes upon that safety by laying emotion out in front of themselves, thereby placing it onto others around them.

Since fear of being unsafe and vulnerable to “predators” is directly related to fear of death in many ways (and I’m sure I don’t need to point them all out) than it follows to say that the fear of mimes is also a fear of death.
