what are your feelings on dream sans? (we don't know much about undertale aus hopefully we found info on the right one)
You did!
To actually answer your question - depends on the Dream. As a character, I find him fascinating and compelling (if poorly treated in canon, but canon butchers all potential to be three-dimensional and interesting every character in it has), and outside of my rampage I actually do agree with his morals.
If we're talking about fictives, though, it depends. My Dream (Stel) and I don't get along at all. They think I have no potential to change, that every action I take has some sort of self-serving ulterior motive.. it's not wonderful. He also was responsible for the deaths of everyone I cared about.
Other than that, I've managed to become quite close to a few Dream fictives. Leveret from another system and our Shattered come to mind first.
