In the very beginning of the game, April dreams of Arcadia and then "falls" into it and can interact with physical (tree, egg) objects there, just like Zoe's "dream presence" in Dreamfall. This is the only instance in the game that April physically travels to Arcadia without (visibly) passing through a Shift. E.g. in a later chapter, she similarly opens a Shift in her sleep, but still has to wake up and step through it to actually use it. Indeed, her first encounter with the White Dragon (and it was real, since when April revisits the same location via regular Shifting late in the game, you can still see the traces of her previous visit) took place even before April's first definitive Shift with Cortez's help. Unlike Zoe, April apparently doesn't need Morpheus and the Dreamer consoles, eit
