Dues Ex Machina is a plot device that comes out of no where and wasnt apart of the plot before hand. ME3 does tell you about the cruicible and catalyst, but it may have some parts of Dues Ex, but not entirely. Read Nancy Drew where she figures out the mystery by information never given to the reader at all. Read the Foundation books by Isaac Asimov, an ending out of no where just to wrap things up. Mass Effect suffered some bad writing, and my personal preference, that dream sequences hardly ever make for a good plot device. (Kotor probably be the only exception.). But ME series does not have a Dues Ex Machina device. As you are aware of it before the ending.
