Seth texts the details of the bag to Gabe, and that it had disappeared. Then he sends another text with where Daniel is staying, in case Gabe wants to go check out whether it's warded properly or something.

"Well, maybe Gabe will know," he answers. "What were you even doing in the dream? I hope it was less horrifying than what we were up to..." Then again, he doesn't exactly wish Daniel and Lucifer were having a party together either. That would be a different kind of disturbing.
