Strange dream about my dream friends trying to help me out...what does this mean?

When you are at Grandma's house, that means you are going through a change. The people and the Monkey are all Aspects of you. You just see them out there when you are dreaming. That's how the subconscious works. You were cruising your creative landscape where you get your inspirations at times and the Woman Artist who is dead i guess suicide by your description is the emotional creative female anima that is so rare in purest form in creativity now days. You saw her because you have tried to get rid of your own emotions also and they are okay to have. Even when not pretty because they are what makes life interesting in the fine arts. They add the Blues and the Greens.
