The stretch of silence that followed her outburst set Rey ill at ease, and she wondered whether Luke had actually known at all, or if he'd only suspected, or if he was completely and utterly confused and searching out her thoughts for answers now. But she didn't feel him prodding about in her head - not that she knew whether or not she could - and his response when he finally did speak-....

Why was none of this making sense?

"What are you-...?" Her brow furrowed as she tried to parse out his words, only for her eyes to widen as she felt her face go warm again. "You never should have-...? You mean, you dreamed about it too?"

The idea that he thought the shared dream came from him and had absolutely no bearing on Rey's feelings on the matter was something that could be dealt with after she processed this first bombshell.
