It is uncommon to dream of painting with someone. You must really love painting to have this dream. What’s the dream interpretation of painting? You may have an idea which is trying to express itself. Dreaming of painting is one way of reminding you that you need to start this painting, to give expression to the idea.
What if you’re not a painter but had this dream? There could be other interpretations of this dream. maybe it is calling you to take up the brush and start painting. Maybe painting is a metaphor which points to another message. You paint and create a picture. You paint your reality, the way you make it out to be. If you are unhappy with your life, it is time to start painting a different picture. One which is different and in which, you are happy.
