We could take this further and maybe deduce that the first time he saw the kid, the kid might've been real the first time we see him, but not thereafter. If they intended him to be real, Anderson wondering what the heck Shepard was doing at the vents was a good way to cast doubt on that.
Assuming the kid was in his head, I think the most likely explanation is a lack of sleep. I'd be stressed out, maybe sleepless if I'd been through his stuff.
The sacrifices he's made, being killed and resurrected, being scarred by bullets and worse, and finally knowing the end was coming and not being able to stop it.
This was never elaborated and, generally lack of sleep, constipation, irritable bowel syndrome and such don't really play such an important role in a plot.
Also, maybe Shepard was exposed to indoctrination waves in this process, but not enough to fully indoctrinate him. Maybe he responded in unusual ways to it, wasn't affected the same way as others.
The kid was too important not to be symbolic though. I'm not sure what burning trees has to do with it, but there are deliberate connections drawn between the kid and everyone he's lost.
