She's also going to try it on someone who hasn't received anything else besides the pocket dimension, just for scientific rigor. 

The someone else says they're now motion sick on top of everything else but maybe this is good? Maybe it means there is motion?

Do they want a power for beaming an experience into someone's head, so they can beam what they're currently experiencing into her head, see if she can make sense of it. 

Uh, sure, if that sounds good to her for some reason.

Oh it's gonna suck. But it might usefully suck.

They're game.

She gives them the power. 

Here is what it is like to be them:

No two parts of them - no two muscle fibers, bone splinters, strips of skin, tendons or organs or membranes, veins or lobes or nodes - are next to their right neighbors. The eyes are the exception, intact enough to look out on the world, though without the support they would need to foveate or focus. The mind persists, and the nerves make reports to it, without much reference to the bioelectrical dismay and physical trauma that would have killed the brain beyond dead if it weren't now running on pure magic. All of this is painful, but it is not really incredibly so: the sheer incomprehensible noise of the things not being where they belong, a thousand phantom hands and legs trying to complete the fragmented pictures of each separated fingerprint and follicle, somewhat confuses the pain into a background agony that is both credible and less urgent than, per se, being part of an ooze. And it is "part of": the other thing the nerves make claims about is that the victim is enclosed, crowded, violated, forced into a sliding slimy intimacy with every other stranger suffering there, and the fact that a fragment of a tooth or a square millimeter of ankle shouldn't be able to register such a nuanced impression of the soupy misery is absolutely not stopping them from doing it. The ooze that they are is turbid and restless, so this sensation changing is a constantly attention-getting part of the sensorium, unlike the relatively static pain.

Ever since they got the pocket dimension most of this is happening twice as much, except for the touching other parts of the maw-mouth component. That is still only happening once.

And the new powers that are letting them reassemble are maybe, if you somehow manage to pay very close attention to any tiny trifles through all the mess and horror and torment, allowing any bits that slosh right up next to their originally adjacent anatomy to stick back together. Which happens only once in a great while. Maybe a good stir would speed it up.

WOW SHE KNEW THAT WAS REALLY GOING TO SUCK BUT BOY HOWDY DOES IT SUCK. 

Shakily, she picks herself up off the floor, where she seems to have collapsed in a heap. 

She can't really complain. She is actively trying to retrieve these people from the maw-mouths, instead of killing them as soon as possible; this involves a significantly longer period of that, specifically, than she just experienced. Plus now she has any idea what it's like to have that ability used on her hostilely! This is a thing she was aware that Dad did, but he's never done it to her, obviously. Not that it was hostile per se; she literally asked for it. But. Same approximate experience. 

"If a part of you is touching in the pocket dimension, but not in the maw-mouth, can it stick together?"

"I don't know. Probably if it had to be both it would take years to happen even once."
