This is often referred to as Visionary Art. Some of the greatest works of art were created by artists channeling other entities. Many of these artists were not aware that they were channeling. Others called upon different entities to create different styles in their work. Still others went into altered states to create their work.
Many people work out personal issues in their art.
Some of my clients have come to me with drawings asking me to define the nature of the art work. Sometimes I can do that. Usually it is impossible, not knowing the state of mind or conditions under which the work was created. Art of any kind is a wonderful way of self expression. Allow it flow.
