A few days after this dream, a mayfitz knocks on her door and says that Aron had left him holy books which he sold for 400 shekel (=$100) and he doesn't know what to do with the money, so he figures that it should be used towards her husbands trip to Uman.
2.Eliyahu Shalom's son dreamed about Aron Patz being with a group of chaverim that were working on two projects of publication, this was along dream and I don't have the ratzon to type it out, in the dream Aron snubbed them for not taking care of the problems, and then was the harbinger of their success, at the end of the dream Meir Yimini knocked on the door, at first no one heard, he knocked again and said, what no one wants to hear stories of Saba? The dream has a certain veracity to it, as the child didn't have real knowledge of the problems involved in the publication which he retold in detail. Also of note, is that shortly after this dream the chaverim decided to put Meir Yimini's name for remembrance in the new holy books being published.
There are more, but that's it for now.
