Dreams of Prophets are authority in matters of deen but dreams of others are not authority in matters of deen.
Many dreams are outcome of thoughts during day time where as some dreams are visionary and need to be interpreted.
According to authentic hadiths such dreams are 46th part of revelation. We should not share bad dreams with any one and should seek refuge from Allah swt from these dreams.
Good dreams should not be shared with every one .These should be shared with sincere and knowledge ful people so that person is saved from jealousy and wrong interpretation of dreams.
