There is a big difference between thinking back to an earlier time where you try to remember what it was like and suddenly finding yourself at the same place and the same time when the event took place. We call this type of experience “high-fidelity memories” because to some degree you are actually reliving the experience in the present rather than relying upon just your memories to remember what it was really like.
There are a lot of new concepts involved with a camera capable of capturing reality the way you experience it. Concepts used to describe things that no one has ever experienced are not easy to convey. A perfect example is “high fidelity memories.”
