A forest is a land mass that is covered in undergrowth and trees. They usually inhabit thousands of plants, animals, and insect species. Forests are dense and can represent wilderness in a dream.
Positive: Dreaming of a forest could represent God revealing to you that you are in your season of coming out of your wilderness to enter your promised land. The forest could also represent a period of trials or a process you are going through to prepare you for your destiny.
Negative: If you dream that you are lost in a forest, it could represent that God is revealing to you that because of something in your heart, He is allowing you to stay in your wilderness for longer.
(Exodus 3:18; Leviticus 20:24; Jeremiah 17:6).
