All art is subjective. The images and feelings which are created within the mind of the observer as a result of viewing are as a result of their interpretation of the thoughts and feelings which were in the artist at the time of its conception.
If the artist was sexually abused at a lake-side cabin as a child, then their painting of a lake-side cabin is one of terror and fear, but to someone else it is merely a picturesque landscape painting.
Images carry no inherant meaning, message or feeling. They merely use common associations within the general population to create a certain sense within the observers mind.
