They may represent your unconscious or your “mental space”. If you are lost in the woods it may be a reflection of feelings of confusion and lack of clear direction. Also, dreaming of being lost in a big forest it is an omen of financial gain, if you are poor and lost. If you are well off and lost, you will experience loss. A stroll through a beautiful green forest with tall trees show that you will have a period of hardship followed by release from worry and then success in your endeavors.
