Dream Evolution is just a translated name, translated from "Gensou Shinka".

The sole purpose of these new evolutions is to provide the "what if" story to the units, such as "What if Vargas was still alive? What things would have been different if he didn't face Ark?" It's meant to reference sort of the "everything" aspect of the unit. Interestingly, Gumi's translation team couldn't find a word in the English dictionary that replicated this similar thing, but ended up using a Latin root "Omni", which means all, whole, everything. According to Gumi, Dream Evolution is still an accepted term, but they thought Omni Evolution would be the official name to reference the "everything" aspect of the units that have Omni Evolutions, such as the Six Heroes.

Just a fun fact trivia for those who are curious. :)
