If your dream strongly features a doorknob, this symbolizes your opportunities and expectations, both positive and negative. You may be seeking assistance and/or spiritual guidance with a particular situation.
Example: 41 find my way to a door and knock. It is at the end of a cul de sac.
An old woman of about 60 comes to the door. Although old, she is healthy and well preserved. Without a word I grab her in my arms and have sex with her’ (Patrick S). Freud felt that a door, a keyhole, a handle, a knocker, all depicted sex and sexual organs.
The example shows this clearly. Knocking refers to the sex act, the cul de sac is the woman’s legs. But the image of a door has so many other ways of being expressed in dreams and is used very frequently. In the next example it represents the experience of discovenng a new feeling state.
For instance, if one had always been apologetic and now became affirmative, ‘new doors’ of expenence could well open. Example: I come up to a door which I d never seen before, and on opening it, I came across another house fully furnished’ (Mrs R F).
General meanings, depending on the dream, are a boundary; the difference between one feeling state and another; such as depression and feeling motivated; the feelings or attitudes, such as aloofness, we use to shut others out of our life to remain independent or private; being open or inviting; a sense of leaving an environment or relationship—escape; entering into new work or relationships. Someone at a door: opportunity, the unexpected; new experience. Front door: public self; confidence; our relationship with people in general; a vagina. Back door: our private, family life; our more secret activities; the anus. Side door : escaping from a situation, or being indirect. Shutting a door: privacy; trying to find ‘space’ for oneself, the dismissing attitudes or tension we use to shut others out of intimate contact; end of a relationship. Door to strange landscape or world: finding entrance into unconscious. Doorknob: see knob.
Example: 4I am being strangled from behind by a faceless man! I had gone down to lock my flat door for the night when I noticed the door was open. I hastily bolted it and ran upstairs, but unknown to me the intruder was already in the flat’ (Miss H). Here the door represents the censorship the dreamer places between her conscious self and her sexual drives. In strangling’ our own life drive, we ourselves feel cut off from life. ...
