The Fisherman and the Hunter | Walking In the Supernatural.
The dream represents famine which is coming upon the land due to a great water shortage. Dry cracked land will replace where vast waters once were. Farmland crops will fail due to the lack of rain. Long duration droughts will lead to major rivers and lakes drying up around the world.
The skull represents the warning of death, a dangerous situation, even starvation.
The brown blob was the spiritual entity with the voice of famine in the earth. When a famine is in full swing brown is the predominant color of the landscape.
