I don't remember too much of this dream, as my recall has been unusually off lately (despite my dreams being much more vivid than usual)... but what I do remember, I want to write down.

I was driving through town with my family, but the town was on a very steep hill and so we had a very wide view of the sky as we drove down. Unsettlingly, the sky was all deep red and violet, and the world was almost deathly silent. I remember looking out the window and feeling strangely resigned but calm, and I quietly said that if the sky was 'finally' that color, then the world was coming to an end. People in the streets were all very nervous, not knowing what was going on but very concerned about the sky and the strange feeling in the air. I remember looking at my brother, and he looked back with the same expression, as we both understood what was happening, and we were ready for it.
The scene switched around here, and I was at my house, in my room. The sky was practically glowing red now, but there was a shadow to everything, and it literally felt like time was thinning out. I was 'waiting' for something to happen. Suddenly I heard a loud crash in the kitchen, and so I left the room and looked down the hall to see what it was. Dave Strider from Homestuck was standing in our kitchen, wearing his original simple outfit (not his suit or Godhood) and holding his Broken Caledscratch. He had just cut down my brother, and he was crying. I somehow understood that the four kids from Homestuck were being forced to do this, as 'harbingers' of what was happening to the world, because if they killed someone before the world ended, that person would have a chance of being 'reborn' in the new world that was to come. As a result, I knew I'd be next to die... but honestly, seeing that sword had me a little nervous. I turned around and walked back into my room, and opened the window, when I noticed that Jadesprite was floating outside. I wondered if touching her would kill me, as she had a connection to the Green Sun, and as I had died in some strange ways before (yes, even now I was dimly aware of being a reality-jumper) I decided that was the way to go. I began to climb out the window, calling to Jadesprite that if she needed to kill me then go ahead, but there was a sudden green flash and she was gone. I heard another loud crash from the kitchen and assumed it was Dave, so I decided to go meet him after all. We met in the hallway, where he stopped and looked at me, still crying. Jadesprite was behind him. I could tell that neither of them wanted to be going about this killing business, even if it supposedly had a greater purpose, and knowing how much trauma they had already lived through, I felt a very strong empathy for them both. At that I walked over to Dave and hugged him, reassuring him that it was okay, and that I didn't mind dying. He was very tense and shaking badly, and I could tell he was now holding back sobs, but he hugged me back. I remember being dimly aware of the world outside then, which was a deep stormy red, and time was still thin but now it was rushing with a terrible silent roar. I still wasn't afraid, but suddenly it felt like the space inside me was expanding and contracting at the same time, and the next thing I knew there was this blinding red-and-blue flash. I fell backwards, having lost all strength in my body, and noticed Jadesprite looking mournfully at me from behind a now-sobbing Dave. I vaguely understood that she had indeed been the one to kill me after all, but the world was quickly fading and I felt like I was slowly sinking into an ocean. The two kids ran over and knelt down beside me, and Jadesprite (who was now crying too) said that it would all be over soon, that it would be okay. I tried to nod but couldn't, so I said 'I know' as well as I could with my fading consciousness. Dave was too distraught to even try to talk, so Jadesprite continued, hurried now, and told me that I would soon be 'reborn' in the new world, as this one was about to die, and that I needed to let her know what blood color I wanted when I came back. I had a hazy mental image of the trolls then, but I was unable to think coherently at this point, my mind quickly slipping into nothing. In the last second I decided that I'd stick with my personal color, so I choked out 'red' as I sunk beneath the waves for good. I had a fleeting thought that, no matter what my blood color was, all I wanted was for Chaos, Laurie, Genesis, Xenophon, and I to all 'get together again' in the next life... and then everything went black.

I don't remember how the next segment of the dream started, but I do recall being back in the family car with my brother Viral, except it was parked and we were just talking. He was playing something on a DS in the backseat, and I was sitting in the driver's seat, looking through a flipbook of Sonic the Hedgehog characters for some reason. Apparently Viral had full recollection of what had just happened to us both, because he then told me that Dave had killed him, and asked if he had got me too. I explained that no, he couldn't, so Jadesprite did. Viral nodded, then asked me who my Kernelsprite was. Although I hadn't seen one in the dream (besides Jadesprite of course), I replied that it had been Davesprite, but he had been very small, almost pocket-sized. My brother thought this was funny, and I think he actually asked me something about Lord English before my memory cuts out.

The rest of the dream was very vague and unstructured, consisting mostly of me wandering and watching other people, and I will admit I almost had a dream-hack at the end but I caught it and got the heck out of there.

In any case, when I woke up I understood with perfect clarity that the first part of this dream had involved the Scratch. Apparently it worked differently outside of an actual SBurb session, playing out like I described.
Still, I found it highly unusual that I had such a dream... very thought-provoking though.
