What does Voldemort fear?

[Fiat Incantatum]

No: HPFGUIDX 34502

We know from PoA that what Harry fears is "fear itself", but what about 
Voldemort? 

In the graveyard scene in GoF, when the shadows have come out of his wand, 
Voldemort is afraid.  "Livid with fear" is what is in my copy.

What is he afraid of, at that point?  Why is he afraid of it?   What does *he* 
have to be frightened of, anyway?

Is he afraid of them because they're dead? Because they might want revenge? Is 
he afraid of them as individuals or is he afraid of what they represent?  Is 
there something that the shadows (or perhaps ghosts) might be able to do to 
him?

Is Voldemort afraid of death? Is that why he was/is trying so hard for 
immortality? 

Discuss, please, and enlarge upon the idea ... I'd like to hear what other 
people think!
