I too had a dream involving Krystal, but it's got nothing to do with Smash (WARNING: It's a weird one):
It was where Krystal was confirmed in SF Zero (first in a gaming magazine, then in a trailer or something (it wasn't specified)), but she isn't playable, and she only appeared in this weird game mode where each of the other SF members (Fox, Falco, Peppy, and the one nobody likes) was in a part of a ship (in a row-like placement) and when a part gets destroyed, the pilot in there falls down to the ground before struggling in mid-air (like in a cartoon) for a bit afterwards, but Krystal jumps to a new section, like a ninja (there were also a couple times where the whole ship gets destroyed at the same time, and all the pilots, along with Krystal, do that falling gag; I'd also assume that it's Game Over or a loss of a life if all sections get destroyed) (also, sometimes it was show that Krystal has her own section of that aircraft, other times she was hitch-hiking in another member's section). Also (it gets even weirder), at first Krystal was wearing her Assault uniform, but near the end she was wearing a yellow variant of it, apparently due to SF's base being a beehive.
