Karen – It seems a mixture of opposites. And as it is usually a picture of your inner world, I wonder if it is saying that you live in a lot of light, insight and awareness – an yet you cannot get away from the dark side of you. So maybe you need to explore both the light and the night.
It might help if you really identify with the scene and describe yourself as it. So you could star off by saying, “I am night time and am overcast but still light. I am ….” You need to keep saying I rather than ‘It is’ because if you listen to what you are saying, and take time with it, you will be describing what is truly your inner world. See –
