Siman 86

(6.) 5569 [1808/9]: He dreamed that there was a certain Jewish congregation with a leader who was very great in the world. And a decree was issued to kill all the Jews, and the leader hit upon the plan that they must disguise themselves as gentiles. And he went and called a craftsman and had his beard and peyos [sidelocks] shaved off. And afterwards it became clear that it was a falsehood — that the decree had not been issued at all. How great a shame came to that leader! Certainly it was impossible for him to show himself before the world, and he was forced to uproot himself and flee. And how does one exit through the entrance, and how does one hire a wagon, and the like — certainly there was a great, indescribable shame and humiliation for him. And certainly he was forced to remain by some gentile for some time until his beard grew back. This was shown to him as a parable against the well-known one of today etc.
