A game of table tennis in a dream, if evenly matched, predicts that you will easily achieve your current goals. But if the contest was definitely one-sided, you will have to contend with some strong rivalry before you get what you want. These meanings apply whether you participated in the game or only watched it.
Dreams of tennis signify that you are giving and receiving, and participating in the back and forth of love and relationship. This dream can also represent feelings of a competitive banter, that you are keeping score, trying to get your point across, and making sure that your message makes it over the net.
Dreams of a tennis court signify your rules and parameters with regards to love. Also, if you are on a tennis court, then you are actually engaged in a relationship or that you are willing to play the game.
