[At first glance, this dream seems like one of the more peaceful ones. It's a white void, stretching on into eternity, and the space is filled with giant gears, hourglasses and crystals. If you want to get anywhere you'll have to jump from one cog to another, but if you slip through one of the gaps you'll just land on your feet somewhere else. There's the constant sound of ticking clocks and flowing sand in the background, and if you focus on the crystals you might hear laughter and voices.
But the atmosphere is tense and overbearing, like something is about to shatter. The ticking occasionally slows down or threatens to halt before resuming a steady pace. Sometimes the laughter sounds a little more menacing and the voices sound more like screams. In the distance, too far away to be comforting, there's a bird call.
In the center of all of this, the Supreme Kai of Time floats. Sat cross-legged on thin air, she seems to be meditating but she's clearly not at peace. She seems to be struggling with something, and when the ticking skips a beat she cringes. When it momentarily calms, she relaxes slightly but quickly focuses again as some other disruption in the background occurs. The bird calls out to her, but is too far away to reach her and she doesn't even open her eyes in response. It's like all her energy is going towards holding this world together.
Apparently this is what Gods have nightmares about.]

[Alternatively, once she's gotten the hang of all this, she'll be crossing into other people's dreams deliberately. If she can, she knocks first. She's no ruffian, after all!]
