Is a dream, whether positive or negative, after performing Salatul-Istikhara regarding marriage to a specific person, attributed to one's psychological state or to Salatul-Istikhara itself, especially with the sensation of an extremely bitter taste in the mouth or seeing a cat for three days?

A dream after performing istikhara could be a result of the istikhara itself or due to psychological stress experienced by the person performing it, as some visions are merely self-talk. Reliance in istikhara should be placed on a feeling of ease in one's heart and the facilitation of circumstances. As for seeing a cat and bitterness in the mouth in a dream, specialists in dream interpretation can be asked about these.
