Peressa seems less interested in teaching Rebecca her vocabulary than in learning Rebecca's. She introduces herself when Rebecca does. 

Eventually, after enough English words have been collected and posted to the linguist group, Peressa retrieves a spare tinynet, fiddles with it for a moment, and hands it to Rebecca. 

It seems to be open to some kind of language app. The app has the words RABAKA AZ HER above a typing box and a keyboard with the latin alphabet in alphabetical order and a completely unfamiliar layout. If she taps on the text, the box says, "Rebecca is here?"

"Wow I can read in this dream but the spelling is super bad!"

Peressa makes an encouraging noise and taps on the text input space. 

Rebecca types REBECCA IS HERE.

The app chimes brightly and displays another line of text. 

The spelling and grammar are both atrocious. They've got a lot of linguists working on it but the material they have to work with is limited, and to start out with all they have to go on with respect to letter-phoneme correspondences is the letters' names in the alphabet song. But as Rebecca corrects more sentences the sentences do get less egregiously terrible. 

Okay, she'll... do that then.

It takes a long time before the app and/or the linguists are reasonably satisfied with their translation. But eventually Peressa taps into her own tinynet, and a tinny voice says, "Are you alright? How did you get here? Where are you from?"

"Uh, I'm fine, I think this is a dream, and I'm from the Salt Lake area."

"It doesn't seem like you're dreaming from my perspective. What evidence would convince you this isn't a dream? What's the Salt Lake area?"

"I dunno? It seems like it kind of has to be a dream, right. It's the area around Salt Lake City? Which is near a lake. Which is salty."

"There are multiple salty lakes in the world," she points out. 

"Yeah, it's the biggest one though."

She pulls up a three-dimensional rotating world image that mostly matches Earth's. "Here?" she asks, pointing to the Dead Sea. 

"...no... I think that's not a lake." She tries to spin the image around so she can point out the Great Salt Lake.

She examines it. "I think the people there speak," and she repeats the name of one of the languages she tried earlier. 

"Nuh-uh, we speak English in Deseret."

"Nobody in any of my linguistics circles has heard of your language before."

"Well that's because you're a dream."

"I know I exist because I am a thing that knows things."*

*Clumsy translation of the local version of cogito ergo sum.

"Well, yeah, you'd say that."

"I suppose I would. Assuming that either this isn't a hallucination or the hallucination is going to continue indefinitely, what do you want to have happen next?"

"Can I have another sandwich or something? And water."

She pours her a glass of water and assembles another sandwich out of ingredients from a weird fridge. 

Om nom.

"Who's the baby?"
