While I have had a couple of dreams which I think were precognitive in that it would be an incredible coincidence that what happened later was so like my dream, but I think the chances of that are low. And in my case at least it was not as straightforward nor useful, just too weird to be a pure coincidence in my opinion. Most likely, I think, you do not like your current job, and so your dream characters which are part of your subconscious were telling you to consider getting another job. Personally, I do not believe that dreams are prescriptive, they do not tell us what to do in waking life, but you can use dreams to analyze your thoughts and feelings on the matter, and then in waking life you can use the message from the dream along with other thoughts you have in waking life to decide what you want to do with this knowledge, and not doing anything different is a valid option and choice you have in waking life.
