To dream that something is bright, represents divinity, a higher consciousness, and spirituality. You need to honor an admirable person or situation. The dream may also be a metaphor for intellect and someone who is smart. If the brightness is blinding, then it suggests that you are not paying attention to some new insights. White is a promise of success in all that concerns you. White: Purity. Success well earned. To see light in your dream, denotes a clear mind, plain understanding, and insight. Light has been shed on a once cloudy situation or problem. You have found the truth to a situation or an answer to a problem. To see a bright light in your dream indicates that you need to move toward a higher level of awareness and feeling. Bright light dreams are sometimes common for those who are near death.
Lets see. Yesterday was Martin Luther King Day. Did you honor him and the situation?
All three of your dreams have basically the same basic motif. You are up to your neck in situations (work, family, personal) that is placing a lot of pressure on you. The other dreams are more complex probably because you have so many things going on that you can't sort them out. Regardless, I would say this dream is very important, and indicates the way out. That is, you may know the answer, but are not paying attention to those insights. It also says you need to take the high ground in situations. Maybe take a more mature approach???
In one respect it is hard to interpret your own dreams, because you are so involved in them. On the other hand, only you can fully understand their meaning. I view dreams as the subconscious trying to communicate to the conscious mind. In a sense, we have the answers within us, we just need to be in tune. What I do is pick out all the dream symbol words. Look them up in a dream dictionary. Copy them over in the sequence they appear in the dream, and then delete anything that is not specific to the dream. I end results are the first paragraph above. Then I try to make sense of it all based upon my past experiences. So, like I said, only you can know the real meaning. Others can give you insight into the blind spots we all have.
