Because Fey is nosy I like bandwagons, as I've said before XD
It should be noted that since all these dreams were guy's dreams except the last one, the thing she feels weirdest about is being in a human's body rather than a guy's body. One heart... how do you people cope?!?!
Dash's Second Dream: Fred saw several people she knew in this dream, and several she didn't as well as a dinosaur. Baww, Roswell. The 'keep running' thing pinged her for her entire canon XD
Storm's Dream: &hearts Storm. She still misses him... this was a good dream, despite the nightmare-fuel in the form of Daleks that made up most of the dream.
Rook's Dream: Yeah, she has no clue whose dream this was. Vague pings for war, death, lost friends, and she didn't like the fire references so soon after the Great ES Fire. Chess was a big ping.
Alchemy's Second Dream: More running, more fire. She recognized the name, but never got around to telling Alchemy that she had had his dream. :(
Obviously some of these haven't happened quite yet XD
Stigmata's Dream: Having this dream the day she was reborn wasn't exactly a pleasant experience, but at least there wasn't any fire. If she had had a fiery dream after being killed by fire serious trauma would probably have resulted, but as it stands... she was just mildly unnerved. Some pings for someone wanting to destroy the world (Earth?), but she has no idea whose dream this was.
Youth's Dream: She's pretty sure this is Youth's, what with all the stuff about youth and vigor and exercising. Having friends on a mission of some sort gave her pings, and running of course.
Gene-1's Second Dream: Pings for being in space, and for loss of loved ones. She recognized Aurora's voice in the dream, and of course she realized it was Gene's dream.
Crow (Itachi)'s Second Dream: Oh, man wtf was that. She will be looking at muffins and other baked goods very funny for a long time to come after that dream... once she is over her queasiness and the grossness of the dream, she will probably think about it a lot. Persephone, Cancer... the pile of corpses probably gave her unpleasant pings.
Wiggly's Dream: Pleasant pings! And the weird feel of being in a non-humanoid body. Talking about humans as if they're another species is pleasantly familiar, and seeing aliens as weird-looking as this lot is too.
