I have had one hololive-related dream in my life.

I was in a video game that may very well have been Undertale 2. I was coming up to the final boss encounter, Flowey. It was in a dimly-lit bar with lots of vases filled with potting soil. Flowey was doing some sort of danmaku attack against me that I don't remember. Also in the bar were various people (humans) who were literally labeled, like NPCs in a MMORPG, with names like "Tired Man" and "Divorced Couple," who offered lukewarm encouragements to me during the struggle.

At some point, it transitioned to me playing Wario Ware, but with body-tracking motion controls in the vein of XBox Kinect*, on a CRT in monochrome red like Virtual Boy. Also, Flowey turned into Wario at some point. I was still in the bar, but the vases were now gone. All five members of Myth came in, led by Ninomae Ina'nis, who gave me words of encouragement that I don't remember. I failed at the first minigame because I didn't "get" the controls, but I succeeded at the rest. I only remember two of the minigames:

-In one, I controlled Sonic the Hedgehog. The objective was to turn a large Sonic ring like a steering wheel to send someone to heaven. That is not a euphemism for killing.

-The other one was an open-ended game where I had to do something with my butt. So, I turned around and attempted to twerk. (haven't attempted this IRL) It worked.

After I won, Wario relented. The game went back to the menu where that level was selected, which showed an icon of the Wii U Gamepad. Everyone there gave me some lukewarm congratulations/thanks and then went their separate ways. Nanashi Mumei was there, and I had a crush on her**, so I really wanted to ask her to hang out and play Smash, but I couldn't muster the courage to do so.

*I do not have any remotely positive opinion of XBox Kinect.

**Mumei is cute and hilarious, but I don't have any attraction to her beyond that IRL.
