To dream about your spouse partner means that you are thinking a lot about certain person. Perhaps you spend a lot of time together, therefore you even dream about him/her. Alternatively, people who miss their spouses dream about them as well, because of the time they havent met or simply are very much in love. If you see someone being your spouse partner, but in reality this person is not your spouse, then it could mean that you have a crush on this person or you simply adore the features of him/her and wish to have them in your partner. Sometimes we dream about your ex-spouses, which is very normal, because the stimulants we are surrounded by such as familiar place or the food that was eaten together with that person reminds us of our ex-spouses. In this case the dream means nothing.
