( Honestly, she doesn't entirely understand it herself, she's never held onto another person's vision like she did for him. She was just going to hold onto it until he requested it back like he asked her to. But this was the first time it's ever happened and she wasn't sure about how else to explain it. It wasn't very reassuring to see him just as perplexed as she was.

Giving slow nods to his first two questions but his last one she had to give a light shrug of her shoulders. Ever since she'd woken up after being separated from her brother she only had reoccurring dream, reuniting and then the reunion happened.... And soon nightmares were mixed in. But she never had a dream about anyone here in Teyvat. )

I don't know if it came from your Vision... All I remember is my dream black and your vision spinning in front of me before I saw some memory of yours while escaping.

( Even with her talking out loud about it to another person, it felt like such a stretch, as if she was playing a prank to spook or creep him out. Perhaps recounting her last 'dream' of him will help him understand she wasn't lying to him. )

Last I saw was your secret plan in action, you sneaking passed the guards into the abandoned tunnel that was rumored to be haunted. And then you swimming, then you waking up to a giant whale.... That's it... It's never happened to me before.

( She gave him a shake of her head at his last question, but based off his response to this it has never happened to him either. So, who knows what happened. Perhaps maybe she can ask Nahida the next time she's in Sumeru? )

I was wondering if this had happened before for you, but judging by your response, it never did.
