We were dreaming.

A respected rabbi got on a ride and said that he had been approached with a question about a man whose father came to him in a dream on the night of Shabbat and Shemini Atzeret and told him to run away, etc.
In the end, there was indeed a slaughter at that place.
A few days later, I see that it is being advertised about another rabbi who has all sorts of actions in his seminary, some of which cast doubt on whether or not this was a parable.
 
What do we see?
Is someone here inventing something?
Maybe someone wasn't accurate when asked?
Were they both asked? (One was previously a student of the other.)
