There are superficial dreams, and dreams that really have a meaning.
The superficial dreams are those, which are created by bodily reactions, indigestion, overfedness etc. These you don´t need to take into consideration.
The other dreams are signals from deeper layers of consciousness. Such signals have with the separation of the observer and the observed to do, the disproportion in relationship with the surrounding world, and the Now.
You don´t need to go through any process of dream interpretation in order to reach to the subconscious. If you the day through are yourself and the surrounding world present in passive listening, yes, then you will not at all dream.
Then there will be a presence of something, which not is hidden, because the mind is empty and creative.
