It seems from ??”? that one should fast for a disturbing dream and that it’s something to be taken very seriously. However, in the text for ???? ???? (which I think you’re supposed to say the morning following a disturbing dream), the 3 friends say to the person who had the bad dream to go in peace, eat bread, and drink wine (at least according to the text in Artscroll). Does saying ???? ???? replace the need for a fast? Otherwise, why are the friends telling the person to eat and drink if he should be fasting?
