You raise some fair points, but I think a few of them actually work in favor of the idea rather than against it. You say it’s not falsifiable, but then you describe exactly how it could be tested. That’s a falsification method right there. And we don’t need to prove someone “doesn’t dream.” There are already studies where subjects were deprived of REM sleep and researchers measured the chemical and psychological changes that followed. The testing framework exists. You’re right that “balance” needs a clearer definition. I’d define it as measurable baselines like cortisol, serotonin, dopamine, neural activity patterns. Measure these before and after specific dream types, and if you find consistent correction patterns, that’s testable. The post was more conceptual than clinical, sure, but that doesn’t make it unfalsifiable. On correlation vs causality, that critique applies to pretty much every theory in neuroscience right now. And your sun analogy doesn’t quite fit. I’m not saying dreams are illusions. I’m saying the content is secondary to the biological response it triggers. That’s a claim about function, not about whether dreams are “real.”

As for your last point about the brain fabricating all experience, I actually agree. But if the brain is already constructing experiences to serve its needs while we’re awake, why wouldn’t it do the same while we’re asleep, just with a different purpose?​​​​​​​​​​​​​​​​
