As pointed out upthread, we cannot disregard information from valid stories because we don't like it or pick and choose which part of it to take. If this particular dream was not challenged in-universe as being inaccurate, we cannot challenge it either. (It is not enough to have unrelated stories providing alternative accounts if they do not directly specify the dream to be inaccurate.)

On the other hand, there is nothing wrong with qualifying where the information came from. Anyone who feels strongly that this information is suspect can point out (in an accurate manner) that it is derived from a dream. A clever choice of qualifying words can convey a possibility of doubts without directly contradicting the narrative.

Again, as pointed out upthread, this is far from being a unique situation that we doubt things that are said in-universe. One of the more obvious recent examples is the Twelfth Doctor calling himself "Basil". The current description of this is "The Doctor claimed his first name was Basil when questioning Osgood about what her given name was." The doubt here is seeded into the word "claimed", which bears the connotation of stating without basis.
