When you win a cruise in your dreams, it indicates your desires to travel to different places and get away for a few days from the everyday work week. Your mind is telling you to take care of the responsibilities on hand, and start planning for a cruise. Winning a cruise may not be possible, but planning for one and making the cruise happen is nothing short of the possible.
Also in the cruise, the places you visit should be exotic and help to re-energize you.
