I have actually had one lol
It wasn't ANIME but a game so....Close enough..It was Kingdom HEarts..So yea even closer..
Anyway, I was taking the role of Sora though..It was awesome. I was fighting Xemnas in a back yard of some sort. But the best part was in the middle of fighting I was like "Woa woa, wait..Pause.." then I went into the KH pause menu..Except, it was more transparent but you could still see the menu..Anywho, I went into my weapons and exchanged my Kingdom Key Keyblade to the Fenrir Keyblade and said "Ooohhh, aaawwweessooome >
" then I SCREAMED, "UN-PAUSE!!" and faught him with an evil smile, much like the one you see on Kid Buu's face durring the end of Dragonball Z.
Great dream if I do say so myself ^_^
