Like many artists of her era, MacIver often explored the realm of sleeping and dreams as an avenue into other consciousness and deeper truth. It is perhaps because of this focus that she was often, especially early on in her career, wrongfully categorized as a surrealist. MacIver painted her dreams and visions into scenes of everyday life, the resulting works taking many forms and styles throughout her lifetime. The great variety of style throughout her career makes her a consistently difficult painter to categorize, as you can see in the unexpected, fairly figural painting of Lloyd Frankenberg sleeping below, in contrast to the dreamy, ghost-like visions that she would begin to paint in the 40s and 50s.
