Old Man. How do you simply state that “I myself maintain that it was a dream”. Why this story in the gemora. Why don’t you say the same thing about any story that the gemora says that you hold cannot be true. The gemora doesn’t say anything about a dream, but is says that this happened.
And there are two characters in this story, so whose dream was it. You are confusing this with places that an amorah says the term “chozoh” as in he saw, which can be interpreted as seeing in a dream, as this is the term used by nevuah, like chazon yeshayahu.
You are getting very close to being a mal’ig al divrie chochomim, in saying that what they said did in fact happen could not have possibly happened.
As to calming down. The reason that you should be ashamed of yourself is for stating that the gemora says something when the gemora says the exact opposite. It is your responsibility to make sure that you are not misleading a bunch of people (and you did because apparently everyone believed you)into believing the gemora says something that is completely false. You could have said that you heard that there was a gemora, but you knew that this wouldn’t mean anything. So instead you declared that there is a “well known gemora”. Shame on you.
