I keep thinking of Dragonball Z when you say mana ball lol. Most of my dreams are in dark buildings and my own house at night, I wish I had more dreams in a sunny field like yours was.
Were you lucid? Sounds pretty exciting! My dreams tend to be boring unless they are nightmares or I start realizing its a dream.
If I was you, I would write down the key points of your fragments. You don't have to get every detail of your fragments. But this may help you to find some dream signs.
