The following was related to Rabbi Uri Silver [a rebbi at Rabbi Senter’s yeshiva] by Rebbitzin Wolbe on February 29th 2012. [This story has been verified via Nava at Dreaming of Moshiach, who called Rebbetzin Wolbe to confirm details]
Three months earlier Rabbi Shlomo Wolbe [author of the Alei Shor and the leading Mashgiach of the last generation] appeared in a dream to his granddaughter. He was very excited and animated - which she mentioned was uncharacteristic for Rav Wolbe who always spoke in a very controlled and measured manner. He was speaking very quickly and was looking upwards [also uncharacteristic] and he said that "Mashiach is ready to come, if people would be “concerned for their friends like they are concerned for themselves” then Mashiach will come immediately."
Rebbetizin Wolbe mentioned that it is a mitzva to publicize this dream!
