Not to come again with my random ass headcanons/rambles but this time is about the blorbo ever, Dream (who I use they/them pronouns for, spoilers lol)
Hear me out. Iirc it's canon that Nightmare doesn't/can't lie; he can say half-truths, he can omit details, but at the end of the day, he can't say something that is wholly 100% untrue. Right.
Then what does that mean for Dream, who is entirely his opposite in energy? Over time I built my headcanon as being that Dream can't be fully honest, ever, in juxtaposition to their brother.
This can be taken a couple different ways; Dream's whole "personality" is a bit of a fabrication after all (not as in "they're secretly evil" way ofc), they're a "public figure" of sorts that needs to look/appear/be a certain way, it's more rigid than it looks, that's enough of a lie as it is, and they definitely have trouble separating themselves from the idea of what "Dream" is.
After all, if you strip them of what they represent (hope, salvation, safety, care, they're a hero, a savior, a healer and a helper) all you get is a broken guy who, at 6yo, lost everything (and even before that, was only loved as an object to be used and asked for favors), got turned into stone for 494 years (while staying semi-conscious, mind you! they could feel what was going on out there!), woke up to Neil being dead (he's mortal, duh) and Lanny training them while absolutely hating them (being said that she was harsh enough to make them almost lose hope. lol.), like, the cptsd is very real and Dream would rather die than be honest for a second about who exactly they are.
They're Dream [The Guardian of Positivity], Dream [Child of Nim, Guardian of Feelings], Dream [Protector of the Omega Timeline], hell, they can even be Dream [of the Star Sanses] before they're [Dream], you know?
Nightmare's honesty is devastating as someone who wants to completely erase his past, it follows him in his every word; and Dream's dishonesty is also devastating, as someone who desperately wants to go back to the past, as it stays out of reach and mocks them.
...Alright sorry it's late and I'm Going Insane alright
(Edit, in the "canon facts about Dreamtale" posts it also says that Dream often lies to people to keep them happy which is the diet version of this post if you will sdfhjbgsdfhjbgsdf)
