Our brains don't store memories like computers store files -- they recreate them every time we remember. When we recall something, different brain regions are involved in reconstructing the experience, combining sensory details, emotions, and context into what feels like a replay of the original event. But this means our memories aren't perfect copies -- they change slightly each time we recall them, raising questions about how reliable our memories really are. If our memories are constantly being rewritten, can we trust what we remember? And are some types of memories more reliable than others?
