A deck in a dream is often attributed with being a “reasonably safe place, or support” or “something to stand on.” Additionally, it can be seen as how one manages their feelings and how they relate to their feelings of control.
Thus, when dreaming of a deck may symbolize an attempt at managing one’s emotional experience in some way, most often by feeling more informed about telling the truth about oneself and your emotional connections with those around you. Dreaming of a deck may also symbolize an emotional connection that might be present between the dreamer and those in contact with them at the time.
