Hyuuga Elders - Nothing very distinct about them, just a shadowy group of people more or less silhouetted, features very dimly visible -- other than merciless white eyes, of course. Have to know who they are. Their presence, as a nightmare, induces feelings of extreme fear and paralysis, and a stabbing, agonizing pain in the forehead.

Imprisonment - He's trapped behind a translucent veil of some kind of power -- what it is, he doesn't know, but he can see anyone else who's with him (either the other mission participants or illusory companions that are part of the nightmare) walking away, not even realizing that he's being held behind. Their voices comes clearly to him, but they cannot hear him.

Failure - This is subtle, barely a monster to fight, but more like an overlay on other dreams that tarnishes everything he experiences. Anything he tries to do fails. Anything he touches crumbles away to dust, anyone with him turns their back on him, bitter and betrayed by his inability to help them. While this nightmare is in effect, he becomes clumsy, his words lack grace, and his strength drops to nearly nothing. Everything he wants to do is impossible, and even desiring to do anything at all is futile.
