Is a dream in which a wife sees her father pouring water on her, and she feels something leaving her and she shudders in fear of it, considered an omen of something or is it not to be heeded?

Interpreting dreams is not within the purview of this website. If one sees something disliked in a dream, let him spit lightly to his left three times, seek refuge with Allah from its evil and from the accursed Satan, and not tell anyone about it. Then it will not harm him.
