Pokémon world, of course.
Last night i had a dream that it was dark outside, and i saw some light that kinda looks like when a pokémon is evolving. I saw every single animal turning into a pokémon. The next day, in my dream, i woke up and i saw three pokéballs and a pokédex lying in front of my bed. I scanned them with the pokédex and they were the starter pokémon from Johto. I took Chikorita. Then, my father took us to the forest and we saw some wild pokémon there. I captured about 14, but i cannot remember wich ones. But i do remember the feeling i had when i was batteling the wild pokémon. It was an AMAZING experience.
(and i know, there would be some errors if that would happen)
