Dreaming of bait means you are aiming to acquire something that you have set your eyes on for awhile. If it is a promotion that you want, then waiting for your boss to take action is not the best route to go. Instead of baiting someone to take an action on your behalf, it is better to assertively request it yourself.
If you dreamt about using bait to catch something, this could potentially be interpreted as a reflection of your own desire to attract or achieve something in your waking life. It could be a sign that you are feeling ambitious or motivated, and that you are taking steps to achieve your goals.
In your dream, the bait could also represent your own feelings of desire or temptation, or it could represent someone or something in your life that is trying to lure or attract you.
