I had a dream that I was at another kendo tournament, except magic was involved in our fights as well. Apparently there was a powerful and evil kendoka present, although very few people knew about her. She accidentally got sucked into a portal leading to an alternate universe, which was catastrophic because if she met her alternate self and teamed up with her, they would be unstoppable. My senpai created another portal in the ground using some potions. I was going to go in myself, because I had a sword that was capable of draining the evil kendoka's power, but my senpai insisted to come along. We were still fighting her when I woke up.
Your dreams are like cheesy anime.
You should keep a dream diary and sell your notes as collections of short stories.
