People always forget that things are oriented randomly in space. And in fictional situations where it could make a big difference, it almost never does.
Another similar case is time travel. If you go back in time six months, the Earth is going to be on the other side of the sun. I hope you brought a space suit. Of course, this is if your time travel is relative to the sun. In reality the sun moves almost 4 billion kilometres around the centre of the Galaxy in 6 months, so good luck even figuring out where it is.
It does actually make sense for fiction to completely gloss over this and assume you arrive in the same place on Earth - otherwise time travel stories would be extremely boring.
The overall moral here is you can get overly technical if you wish, but don't let it get in the way of a good story.
Commentary by memnarch (who has not seen the movie)
Hahaha, if this really is a Force Phonecall, it's a quite amusing one! Admittedly, the dialogue is probably helping by pointing out how ridiculous it is, but still. Rey gets the feeling of Kylo's presence or whatever. Immediately tries shooting him and goes off elsewhere. Kylo responds by moving about where he's at (a very poor showing for ESP) and looking like a buffoon while he does so! At least it appears there's no minions to get caught and make things really awkward like the turbolift like last time.
I did think of a way separate scenes could work for this scene. There's been a fair amount of visual info that still makes me think it's a Force Call at this point, but there's a small chance. Going with the assumption that there's two scenes, Kylo could be hearing things out in the corridor in a later scene, possibly a Resistance attack or just Finn and Rose snooping around. Rey, on the other hand, is getting harassed by Luke with "Force Distraction" as the indirect discouragement before isn't getting through. Mind you, that would assume Luke still doesn't want anything to do with Rey in spite of the R2-D2 scene on the Falcon and following bit with Rey.
Rey: Maybe I imagined that? I head outside for some fresh air.
Kylo Ren: Where are you going?
Kylo Ren: I try to follow her presence.
Rey: Yeah, good luck with that. Given random orientations in space, me moving horizontally is almost certainly angled upwards or into the floor where you are.
Kylo Ren: Or it’s relative to our own anatomical axes.
Rey: That’d be too easy!
GM: Let’s see, arbitrarily complicated or too easy?
GM: Sally, roll Force Sense.
Kylo Ren: 15.
GM: You track the link into a corridor.
Kylo Ren: I use Force Suggestion. You will tell me where you are.
GM: -5 penalty over this channel.
Kylo Ren: Ugh, 6. Can’t I get a break?
Rey: You just got a big one!
