At times one might not know whether or not to actually believe the stories one reads about our gedolim, and this story is an example of that...

Kikar is reporting about Rav Chaim Kanievsky's siyyum during the 9 Days. Besides for his annual siyyum of Masechet Yevamos on the 8th of Av, Rav Kanievsky woke up from a nap on the afternoon of 3 Av and asked his grandson to bring him wine. With wine being a no-no during the 9 Days, Rav Kanievsky realized his grandson was a bit surprised at the request, so he explained his request saying that he was about to make a siyyum for having finished Massechet Brachot in his dream.

When the incident was told over to Rav Shteinman, he said that there is no doubt that by Rav Chaim Kanievsky who has everything laid out before him and has the ability to say that he finished a massechet of gemara in his dream, he definitely will have actually finished it and can have happiness for it.

True story or not, I don't know.

I do know that:
1. they do not tell such stories about me
2. I do not finish, or even start, tractates in my dreams. I usually do not remember my dreams when I wake up, but when I do they have never been like this dream of Rav Kanievsky

I do wonder, assuming the story is true:
1. did he finish the entire massechet in one dream or was it over the course of a series of dreams throughout the year?
2. if he did the learning in the dream, maybe he should only make his siyyum in a dream as well
