Besides insight, to see light in your dream might represent illumination, clear mind, guidance, and plain understanding. Is the light being shed on a once cloudy situation or problem?
Lights often suggest a beacon to follow and are indicators of the divine, the soul, and life itself. You might also consider the color of the light. For example, a light blue light might reflect intuitive awareness or be spiritual in nature. This is also true for violet or indigo. Red light may reflect passion or danger. Yellow light can be about lightness or hopefulness. A rainbow of light can represent an awareness of the beauty of life in the midst of problems and difficulty, be a visible blessing, or represent happiness and hope.
To see a bright light in your dream, might indicate that you need to move toward a higher level of awareness and feeling.
Light is often a symbol for the creative point in ones awareness, of bringing new light to consciousness.
Bright light dreams are sometimes common for those who are near death. To see soft or shadowy lighting in your dreams, indicates feelings and thoughts from the primal aspects and less developed parts of your unconscious. To dream that you cannot turn on the light, indicates a lack of insight and perspective on a situation, or a feeling of paralysis with regard to what you need to do in a worrisome situation.
To see a glow in your dream, might symbolize enlightenment, happiness, or that new light has been shed onto a situation. You might have gained a fresh perspective and reached a some measure of understanding. Someone glowing can also suggest that you look at this person in a new light, from a new perspective. They may also represent a spirit guide.
To see an aura around you or someone else, might suggest that some important information is being given to you in the dream and you need to pay close attention to the message, or that you need to draw on this energy for strength.
Some say auras or light hallucinations in dreams can warn of an oncoming migraine. These auras can also indicate an on-coming nightmare.
To dream that you have a halo might signify that you are a perfectionist. It may also represent some significant spiritual development and supernatural energy.
If something is sparkling in your dream perhaps it’s a signal to pay attention. Consider the pun, “all that glitters is not gold” e.g. don’t be fooled by all the glitter of something because beneath it all may be commonness or deceit.
It could be a feeling of joy, or happiness or a desire for the same. It may also symbolize something of value.
