You are fairly sure your vision was not allegorical. However, as I mentioned before, it's probably too late to do anything with it now so I wouldn't dwell too much. It related to Gallagher and whilst you have been eceptionally obedient in not looking into past events, (one of the mysteries of the episode is exactly WHY he is going along with Sienar, related in turn to what actually happened to him in times past), I was actually assuming you would pry (especially Andro). Your vision gave various clues as to his storyline but there's really no time to suss that out now.
Meanwhile- no planets have blown up and Roan's not THAT good for a generic sense. No, these beings are right here.
