Dreaming about a couch could mean that you may have a need for some rest and relaxation.
The couch also has other symbolism.
For example, it could be an object that brings up warm memories, such as those of your first love, whom you snuggled and first kissed. Additionally, look at all the details of your dream and try to determine if your couch is symbolic of an analyst’s “couch,” such as Freud had. Old dream interpretation books offer a somewhat strange but curious meaning. They say that the couch may be symbolic of a false sense of security and that you should listen to the advice of those that love you!... The Bedside Dream Dictionary
