I gave you a brief description of the theory that I often refer to in the other question that I answered about your dream, but this dream goes a bit deeper into the psyche. Maintaining the use of the Jungian theory that I described before, I want to share with you about the symbols that Jung described that tend to exist in a dream.
"Jung identifies seven such symbols in what is referred to as the major archetypal characters:
1. The Persona is the image you present to the world in your waking life. It is your public mask. In the dream world, the persona is represented by the Self. The Self may or may not resemble you physically or may or may not behave as your would. For example, the persona can appear as a scarecrow or a beggar in your dream. However, you still know that this "person" in your dream is you.
2. The Shadow is the rejected and repressed aspects of yourself. It is the part of yourself that you do not want the world to see because it is ugly or unappealing. It symbolizes weakness, fear, or anger. In dreams, this figure is represented by a stalker, murderer, a bully, or pursuer. It can be a frightening figure or even a close friend or relative. Their appearance often makes you angry or leaves you scared. They force you to confront things that you don't want to see or hear. You must learn to accept the shadow aspect of yourself for its messages are often for your own good, even though it may not be immediately apparent.
3. The Anima / Animus is the female and male aspects of yourself. Everyone possess both feminine and masculine qualities. In dreams, the anima appears as a highly feminized figure, while the animus appears as a hyper masculine form. Or you may dream that you are dressed in women's clothing, if you are male or that you grow a beard, if you are female. These dream imageries appear depending on how well you are able to integrate the feminine and masculine qualities within yourself. They serve as a reminder that you must learn to acknowledge or express your masculine (be more assertive) or feminine side (be more emotional).
4. The Divine Child is your true self in its purest form. It not only symbolizes your innocence, your sense of vulnerability, and your helplessness, but it represents your aspirations and full potential. You are open to all possibilities. In the dreamscape, this figure is represented by a baby or young child.
5. The Wise Old Man /Woman is the helper in your dreams. Represented by a teacher, father, doctor, priest or some other unknown authority figure, they serve to offer guidance and words of wisdom. They appear in your dream to steer and guide you into the right direction.
6. The Great Mother is the nurturer. The Great Mother appears in your dreams as your own mother, grandmother, or other nurturing figure. She provides you with positive reassurance. Negatively, they may be depicted as a witch or old bag lady in which case they can be associated with seduction, dominance and death. This juxtaposition is rooted in the belief by some experts that the real mother who is the giver of life is also at the same time jealous of our growth away from her.
7. The Trickster, as the name implies, plays jokes to keep you from taking yourself too seriously. The trickster may appear in your dream when you have overreach or misjudge a situation. Or he could find himself in your dream when you are uncertain about a decision or about where you want to go in life. The trickster often makes you feel uncomfortable or embarrassed, sometimes mocking you or exposing you to your vulnerabilities. He may take on subtle forms, sometimes even changing its shape.

So with explaining these, and not being too aware of any major transitions that you are processing, let's explore the dream a bit. I am leaning toward the symbolism suggesting the shadow or a trickster in your dream. It sounds like you may be processing feelings of being overwhelmed right now. You may feel that internally everything really is swirling and you may feel that you are under a great deal of stress and feel that you have very little control. You are not aware of why it feels that you are unwanted in your home, you may have guilt or anger at yourself for leaving your child at daycare, you may have felt that you were very confused about the state of affairs. interestingly there could be something that has happened in your life that you are experiencing remorse and feel that you should accept some sort of responsibility-- maybe you feel that others also feel this way. "To dream that objects are moving on its own or that switches and electronics are turning on/off or some other paranormal activity indicates that you are refusing to take responsibility for your actions. The dream is also saying that you tend to let things happen instead of making things happen." Maybe the dream is suggestive of being more independent. Maybe you feel that others do not notice your appreciation and so you would assume to take more of an active role? Forgetting your child is what suggests to me that you feel overwhelmed-- one, that is usually a parent's worst fear, and two, a parent would experience a range of emotions after something like this were to occur! But, it sounds like your friend stepped in and supported you, suggesting to me that although you at times feel overwhelmed, you do have strong people in your life willing to help you when needed!
