The scenery was warped, surprisingly yet unsurprisingly. She'd seen something similar of course, but it hadn't been like that, of course. It was going to be difficult to navigate the space, something she'd been expecting, but she had counted on the fact that with few targets actually there for her to reach things would still be sustainable. She was surprised to see many more possibilities than the few she'd been expecting, but it was not going to be as much of an issue as it might have under different circumstances, as all of them were clearly different from the ones she was interested in.
She had a guess as to what all those other spaces were and where they had come from. A terrible, frightening guess she had neither time nor will to explore and confirm. Yet as she brushed past a few of them on her path towards her desired destination, she couldn't stop herself from gazing inside. Not willfully so, of course. She literally could not stop the flow of information born from contact, the osmosis of data she'd never learnt to deal with. She did not look, but images still flowed. She did not wish to listen, but sound still came. It all but confirmed her fears. There was pain there, suffering and madness, shadows lurking and swallowing minds whole. Then nothingness.
She ignored them, as best as she could, and she forced herself to proceed towards her targets. They were close, far ahead, and both looked worryingly unhealthy. Fluttershy's dream was enwrapped by what Rainbow had already seen before, and only there partially realised the nature of. She realised then that Luna had withheld information from her, and realised the why of it as well. But it was no time to become angry or bothered by that, so she didn't.
Applejack's dream was victim of its own strain of malady. It looked frozen, the surface opaque and thick and cold. She wondered if she'd even be able to enter it while it was in that state. She tried to touch it and found herself connecting with it as if it was a solid surface, like a glass sphere suspended in the air. Nothing passed through, not even as she attempted to press on. She didn't have the means to investigate further, and she'd have barely had the time for it at all. Knowing at least Applejack was still alive was good enough.
She turned to Fluttershy's dream instead, and headed towards it. She had to maneuver herself carefully, looking for an opening that would allow her access without getting her in contact with the parasite growing all around it. She found it eventually, and with brisk carefulness she passed through the edge.
There had been wind outside, some form of it at least. The inside was not much different, and only more grounded. It was a proper sea storm she found herself in the middle of, if of course a purely mental one that only manifested as such. She began to look for Fluttershy among the cacophonous mayhem, trying to navigate through the maelstrom of her overcrowded, scattered and battered mind.
