dreams are personal, so its best if you interpret them, as you might love snakes, but a generic interpretation would come back negative. its good to learn about the history of psychoanalysis and pick up a book with some interpretations to help you, but ultimately, you should have a 'feel' for what the dream means. the subconscious works in symbols, so don't expect it to come right out and say 'your best friend is trying to steal you boyfriend' [example] you will see a fox tricking you into things and getting hurt. [again, example]
above all, keep in mind not every dream is cause for alarm. dreams can be fun, and a lot of the time they are. sometimes a dream is reoccurring or so vivid, you can't ignore it. in these instances the dream should be looked into, but take it as a guide, not an omen.
