This is a combination of what Juranium and Shubhankar Kulkarni suggested in their contributions. While I think that making physical 3D models to represent various important moments from your past might be too complicated and unnecessary, making VR representations of memories that you treasure, want to keep from forgetting, and even experience more clearly and vividly seems like a good idea.
For conversion into a VR space in which you can look around using a VR headset, it's best to take 360-degree panoramic images or at least take many pictures from different angles which you or a dedicated software could stitch together to create a VR tour.
But even if you want to turn an old memory into a VR experience and just have one picture representing it, it's also possible to turn it into a 3D image by adding an illusion of depth with dedicated software. You couldn't look around in such a case unless using 3D modeling to recreate the rest of the surroundings from your memory and adapting the colors to the color panel from the picture, but nevertheless, it's better than nothing.
You could also add other sensory input - sounds and possibly even smells and touch to make the experience richer. It would be cool if in the future neuralink-like devices could convert memories into sensory VR models directly from your neural circuits.
