I never said that Ellone planted the memories,Skyblade.
I will explain step by step and in chronological order.
1-They LOOSE the memories.
2-Ellone send them back to their childhood(it probably was when they sleep at Zellīs house).
3-The dream was stored on their memories.
Also,since it was a normal sleep they didnīt pay much attention to the dream.
4-At Trabia Garden Irvine told them about his childhood.
5-Then they realized the dreams were real.But they donīt remember it being a dream.You know,realizing that the pictures were real made them mistake it with the memories they had before using GF.But the memories were about real thngs since it is a memory of a dream about real things.
So there is no implantations.
Or are you saying that in the world of FF8 people forgot about their dreams?It is obviously false.
Note:Squall had the dreams before going to Zellīs house.This is saw on the game.
