Leviathan pretty much confirmed the entire ending sequence is an illusion.
While I do not wish to discuss the "validity" of this assumption, I will just point to you how your arguments do not relate to your objective, hence making them pointless in this context. I do that only for clarity of discussion. Please be indulgent with the form I will use.

I do not think that "literalists" would argue that Reapers or Leviathans can access their target's memories, since accessing the mind in some way is a pre-requisite for indoctrination. No need to hammer on this nail, but you do not make the proper parallel with anything else but the "kid" which by the way looks "holographic" rather than "real" like the people shown to Shepard in the Leviathan's illusion.

- "I know you've thought about destroying us" ("Your nature will be revealed to us") - Check
A genius is not required to ascertain this, since Shepard already showed severe inclination towards destroying Reapers for 3 games now. But in any case, that does not indicate that the "ending is all an illusion", it merely shows particular knowledge from the Catalyst.

Usually, when someone tries to stand up from a knocked out posture, he usually does so by steps, we very rarely see someone doing an elaborate Bruce Lee kind of move to get up, especially when wearing armor. Shepard's posture "on all fours" is not really showing that everything is an illusion with the "space kid", while I can agree the situation looks different with the Leviathans.

- Shepard's nose is bleeding (The Leviathan mind control causes Shep's nose to bleed) - Check
In Leviathan, there are no other reason for Shepard's nose to bleed, except maybe the deep sea pressure (even a light pops off on the meca). But with the Catalyst, following all what Shepard endured, a common nose bleed is lost among lots of other severe injuries. While a bleeding nose can show the player that Shepard his in some definite "state", that doesn't mean the environment is not the one the player sees.

This does not explain how the end sequence can be a dream, it only repeats something even literalists know.

- The sound that signifies the transition between reality and illusion in Leviathan is the exact same sound you hear when Shepard is zapped onto the Citadel - Check
In the Leviathan scene, the sound is played when Shepard "wakes up" inside the mech, while in the Citadel scene it plays when Shepard pops off the beam, so it can hardly be described as the sound for transition between "reality and illusion", especially when IT proposed long time ago that Shepard pops into dream state
before landing on the Citadel. At best, wording should either be "transition into reality" or "transition into illusion", because if you infer that the sound playing when Shepard "wakes up" in the mech has the same "meaning" on the Citadel, it then means Shepard "wakes up" in the Citadel. You can't reasonably use a fact to prove something and its opposite in this situation. I would suggest trying to find the sounds used in similar situations instead.

... and people have the audacity to claim IT is dead? Laughable. It's more alive than EVER.
I'm not sure a theory can "die", but I understand your point.
