I recently verified this story from the grandson of the couple involved.
My friend's elderly grandmother, Miriam, remarried a number of years ago to R' Shalom Shachne Zohn. They live in Jerusalem. R' Shalom is now in his mid nineties and in his youth he studied in yeshiva in Mir in Poland and had the opportunity to spend four days at the home of the Chofetz Chaim (R' Yisroel Meir Hacohen Kagan). A few weeks ago, in the middle of the night he woke and told his wife that the Chofetz Chaim had appeared to him in a dream and simply said that Moshiach will be here soon. The Chofetz Chaim said that it is time to get ready and to spread the message. My friend's father (Miriam's son) asked his rav, Rav Asher Weiss if this is something to take seriously. His response was that we are clearly standing right before Moshiach, and it certainly should be taken seriously and we should undertake to do Teshuva.
The second story I heard directly from the people involved.
There is a young girl about eight years old who needs a refuah (אביבא מלכה בת לאה) - she is currently in the hospital with loss of vision. Please pray for her. She has been in and out of the hospital for chemotherapy, and she has had multiple complications. A few months ago she had been in a coma for an extended period of time. When she finally came out of the coma, one of the first things she said was, "Did I miss the weddings? Did I miss Moshiach coming?" Her two older sisters were not engaged yet (I don't even know if Aviva knew they were going out), but they both became engaged and were married over the following few months. I was at the sheva brachos. Refuah Shelema - may Hashem heal her along with all the sick of Israel with the coming of Moshiach, Amen.
