358/2 Days *Spoilers* Confused w/ Cutscenes from day 276

I am confused about the two cutscenes on day 276.

Cutscene 1. What in the world actually happened?

Cutscene 2. Did that happen on that actual day, or another day, or did he just dream that?

If there is a reason explaining that inside the game later on, just tell me that.

Also, when Roxas got back on the tower that day and talked to axel, was that what he was talking about? When he said he thought he just dreamed about seeing a girl almost like Xion?

I am so confused....

 

Could you explain what happens?

 

Cutscene 1: Roxas is at destiny islands, and sees Xion with her hood on. Then, Xion lifts her hood, to reveal it was Zexion. Then the young riku appears behind roxas. Then, camera spends around, and Roxas holds his head and hits the ground, and it shows Raxas, Xion, Riku, and Sora, going back and forth amongst them, being in the same position Roxas was; being on the ground holding his head. The camera was like spinning every where.

Cutscene 2: It shows Axel, Roxas, and Xion at destiny islands. Xion says she wants to be with Roxas and Axel.

 

The first cutscene is about Xion, as she changes to everybody. That's a nightmare for her :(

The second, I was confused as well.

 

I could be wrong, but I think the first cutscene is Roxas being overloaded with Sora's memories.

The second cutscene I really have no idea, it seems almost like there's a time lapse between it and the first.
