I've been thinking about the end sequence for a couple days now and I have a reasonable speculation of how it might have went down.
Going on the theory of a mixed hallucination/reality, since Shep apparently never left London, I believe that Harby did knock him out and was still standing next to the Beam. You walking to the beam might be Reaper ground forces/husks taking you closer to the beam. The fact that you shoot some of them down in your fever dream really means nothing since the husks feel no emotion except the Reaper's hate.
Then the citadel dream happens and that is a complete fabrication. You resist Indoctrination through TIM and then pass out again, leading to ANOTHER DREAM which is actually an amalgam of hallucination and reality again.
This time you're standing up of your own free will with the Reaper forces gathered around, some watching you, others guarding you from outside forces like Hammer. Harby takes the form of Starchild. Since it's established that he could control the Collectors from Dark Space, it's not out of the realm of possibility that once he even gets to the Sol system or even before, HE is the one putting spacekid in Shepherd's head from beginning to end. He establishes that link properly when the Reapers get to the Sol system. At any rate, you decide to walk left, you grab some downed cables and electrocute yourself and are thrown into the beam by the Reaper forces to be indoctrinated.
Go into the beam, and the Reapers don't even have to bother to throw you in, you're processing yourself and surrendering yourself to Harbinger without dying first as in Control.
HOWEVER, turn to the right and go to the destroy option and you shoot... something explosive. It could be a car engine or a cache of guns, explosives, and missiles (a reaper armory near the beam, if you will, which could be argued as Reaper HQ). At any rate, it's something substantial but not enough to kill Shepherd. It knocks out the Reaper forces around you and perhaps scatters the others left behind because suddenly Harbinger is stunned (as in "I can't believe he just did that") that Shepherd has completely resisted the Attempt (everybody that did this had to shoot themselves in the head first and die. Death was the only way out). Not to mention Shep could be shooting Harbinger himself in the leg if the aiming is to be taken literal, or in the head if the mixture skews your hallucinations further. If you shot Harbinger when he is at his most vulnerable ( indoctrination attempt at over 9000), then it might cause Harby to suddenly reassess his goal of trying to take Shep alive and the indoctrination attempt would end of Harbinger's accord as well as Shep's own at the same time.
So my opinion is that the end may be mix of reality and fantasy. Shep may not be lying in the rubble the whole time, if we are to guess that this could be a mixture of reality and Shep hallucinating. In fact, Shep may have destroyed one of the pillars of the beam when he/she resisted indoc and chose destroy (or if he had shot Harbinger, Harbinger could have clumsily hit one of the beam pillars himself in his reaction to you shooting him). If one of the pillars is destroyed, the beam might be intermittent or may not work properly and the Reapers can no longer process organics. The light may be there, but the eezo space elevator might be stalled, if you get my drift.
Again, this is just my theory that could work within the theory. I, myself, am not completely sold on it but I see it as a possibility.
