Painter, Yumi and Perception

[Oraiyu]

At the end of the book, Painter paints Yumi on the wall and convinces her to come back. 

Painter applies perception when combating nightmares by painting an alternative existence for them. As Cognitive shadows, they are forced to conform.

The way Painter transforms nightmares into other things is reminiscent of the way spren are affected by perception - only much more extreme. Is perception (and the way the world is set up) the only important factor here, or is Painter using Investiture too somehow?

What's going on here is not Painter using Investiture really. It's the fact that the nightmares have less control over them from another source. Spren have an oversight from Honor, Cultivation, and Odium, and this is kind of leaving them less at the whims of other people's perception. The nightmares do not have that. I'm not going to say they don't have it at all, but Painter is not using Investiture, but the nightmares are specifically more susceptible to what's going on. So for instance, a good way to answer this is if he went and did this for a spren he would not have the same level of power.

Did Painter's perception play any role in helping Yumi, as a Cognitive Shadow, regain consciousness and transform back? Or was he just helping her with a very heartwarming pep talk, while she did all the work mechanically speaking?

It's impossible to know without reading Brandon's mind, but I would think the very strong Connection between them gave him more influence over her than he would have over another Cognitive Shadow.
