Heading to the Hill of Lost Souls

Nemesis is signing to herself a lot, her way of quietly "talking to herself".
If anyone tries to watch, it does look almost meditative as she stares without seeing and just signs away with a mostly blank face:
 
"
*a long series of signs, then hesitation, resigning the same thing a few times before continuing*
*signs can be more hesitant, slower, more repeating of the same signs is continuing*
*signs become sharper, angrier, her face pinching a bit in a glare before slowly trying to force herself to relax again*
*an exhale* Things I know... *slow signing, deep in thought as she continues*
Things I don't know... *faster signing, and a few having more emphasis and frustration in it*
*pausing, kind of tapping her hands together before another sigh and continuing* "Gottcha" *a small laugh, though sad sounding*
"
 
Whenever she finishes what almost seems like a bizarre self-talking meditation, she'll take out one of the children's reading books and move to be alone with it.
 
This can occur when others are asleep, she's driving, or when others are getting ready to and she is starting off out the back of the wagon. She won't acknowledge others, it does seem to be her form of meditation.
