The dark wood and dark forest are important symbols when it comes to everyday life. They make appearances all the time in media.
To dream of dark wood in a dark forest means that you feel a little lost in life. The forest is representative of not being able to find your way. Forests are large and they are complex. If you get lost in a forest in the dark, don't expect to get out until daytime, and it only gets worse when it is a forest full of trees made of dark wood. There is not a whole lot you can do when it comes to this. But if you have a dream of a dark forest and you are scared, not knowing what to do next, then all you need to do is just go through a little bit of deep breathing exercises.
You are having this dream because you feel lost in life. You feel like you had all of these plans for yourself and now they are starting to get confused. You once thought that you knew what you were doing but now you feel like you just have no idea what you are supposed to be doing. If you can't find your way back to the old path you wanted to follow though then you're just going to need to make a new path. It's the only way for you to continue on in good faith.
Being lost in a dark wood means you feel like the world is closing in around you and you aren't able to get to where you need to. You feel cornered and this can be a problem for you. You need to conquer your fears though and face up to them. It's the only way you will succeed and come out on top.
