What does Edward see At the end of Breaking Dawn when Bella shows her thought?

At the end of Breaking Dawn, when Bella shows her thoughts to Edward, he witnesses a multitude of scenes and emotions swirling through her mind. One notable vision that strikes him is a glimpse of their future where he finds solace on an isolated island after Bella's passing. Edward envisions himself sitting alone in solitude alongside a majestic tree at a remote spot by the sea. However, even in this contemplative and melancholic state, he doesn't dwell on sorrow. Instead, he accepts with peace that their love endures beyond earthly existence.
