The symbol of the forest, is an area of animals and usually represents our unconscious, instincts, drives and depths.
Forest dreams thus connect us to our natural instincts. The way we live today, we are very rational, distant from everything instinctual, distant from senses in our body. Therefore, the dream about a forest might feel frustrating and dangerous, but it is advisable to use it as an invitation to connect more to your senses, instincts, natural and animal parts in ourselves.
