A Mass Effect 3 Dream With Indoctrination & / Or Possession & Cerberus

I only remember part of one / a strange / unique / detailed / somewhat confusing dream, but I forgot some of it and some parts are unclear.

It was inspired by Mass Effect 3 again, and I was either Commander Shepard or I was myself playing the role of Commander Shepard or at least someone in a position similar to Commander Shepard; but this world was a bit less futuristic than in the game.

I remember being with a group of mostly orphans young people or just young people, I guess that I was protecting them and helping train them to prepare for the major threat(s) to the universe among other things; but I can not remember the details of this / that, unfortunately.
