Okey okey... But what if Dreamswap but... DINTIS? (I'm really sorry but the image of DS!Dreamare,,,is,,,just,,,p e R F E CT)
Honestly, Dreamswap + DINTIS is not really a possible combination. Trust me, I’ve thought about it, plus a number of other poeple have suggested it. Thanks to their personalities, it’s just impossible, not to mention unnecessary, since DS!Dream isn’t anything like classic Nightmare.
If you look at original Dream, it doesn’t seem all that farfetched for him to just lose hope, give up and just want to be with his (manipulative) brother again. But in Dreamswap, both Dream and Nightmare are extremely opinionated and ambitious people. Nightmare giving up isn’t an option, either. Dream is trying to eliminate him. Not because he wants to, but because he thinks he has to in order to help everyone else. It simply doesn’t work out.
