This is the next scene:

This location reminds me of a location in one of my Episode IX fanfics Force Link:
"Ganeron was a planet in the outer rim. The planet where allies of the Resistance needed her help. But she knew that it wouldn't be long before she and the rest of the Resistance would need their help.
The Millennium Falcon came out of light speed. Just ahead of them was a dark blue planet. From where she sat in the cockpit of the Millennium Falcon, Rey could see that the skies of Ganeron were filled with dark gray clouds. It looked nothing like the dry planet of Jakku that she was used to.
Rey and Chewbacca flipped some switches and pressed a series of buttons. They moved the Falcon towards Ganeron.
As they entered the planets atmosphere, rain poured down hard on the windshield of the Millennium Falcon. It was so hard and thick that Rey could not see anything outside but raindrops.
"I can't see a thing!" She said.
Chewy growled in agreement.
The Falcon began to shutter and Rey feared that they would crash. How could they fly the ship if they couldn't see where they were going.
"The Force will guide you, Rey." She heard Luke's voice remind her. This time it didn't startle her.
She closed her eyes and let the Force guide her. She took the controls and moved the ship just in time to avoid crashing into a mountainside.
Chewbacca watched as she moved the ship with her eyes closed. Then she brought the ship down to land safely on the ground. He had never seen anything like it.
He growled excitedly. "That was amazing!"
"Thank you." Said Rey.
Chewbacca growled again. "How did you do that?"
"I used the Force," She replied."
This location also reminds me of this scene in The Force Awakens:

Which was why I added the location described above to my fan fiction, so that I could add this scene.

Because of this promotional photo, we know that the knights of Ren will be in Episode IX. So it is possible that we will actually get to see this scene happen in Episode IX.
And the location shown in the trailer could be where it takes place.
I really hope that this scene is included in Episode IX, because we never really get to see what it meant, all of the other scenes in her vision have been explained. And since J.J. Abrams, who directed The Force Awakens is also directing Episode IX it is possible that he could include this scene.
