Guardian? Dream

A long time ago, I still remember a dream and wonder, 'What was that about?' This was when I was around 5th or 6th grade in elementary school. I had recurring dreams where I met boys dressed in pristine white formal attire (the kind with a stand-up collar). Sometimes it was near a classmate's house in my neighborhood, other times somewhere at school. I was already writing novels back then, so it might have just been my imagination mixed in, but in my dreams, they each seemed to be guardians of nature. Thus, their white outfits had symbolic colored lines representing their guardianship: a blue line for the water guardian, a green line for the wood guardian. One day, the boy who was the water guardian handed me something like a floppy disk. (Though, I didn't know it was a floppy disk at the time.) Confused, I accepted the floppy disk, and was then sucked into the entrance of the gymnasium at the school I was attending, and then I woke up. It was the kind of dream you have right before waking up from a dream. I didn't understand why I had such a dream back then, but looking back now, it was a time of many changes, so perhaps it was a dream signifying a 'turning point'.
