Cinderella's castle glistening, the cartoon characters laughing, grouping for photos, the many rides with their height requirements, the smells of freshly cooked food, and Bugs Bunny shaking your hand? As you bring that experience to mind, you may have the feeling you are reliving it, seeing your childhood pass through your mind's eye, much like reviewing a videotape.
But the way human memory works is very different from that of a video tape recorder—our memories are actually reconstructions of bits and pieces of information we have obtained over time.
Sometimes those reconstructions are very similar to what we experienced; other times we are "tricked" and remember things differently than how they actually happened.
In Fact, Most of what you recall didn't happen.
