Stabbing wood

A couple or recurring aspects of a dream have made me curious enough to return here and see what others make of them.

For some reason I dream of stabbing wood in my dreams whenever I am fighting something, not always stabbing, at times I break it apart with my hands, but always wooded underneath.

I admit wood is something I do know how to break apart, so my mind might just be using that as I don't know what stabbing flesh feels like.

Another thing is that whatever I am fighting is usually underneath me, and hidden most of the time either by a barrier such as a door or visual obstruction such as water.

I did have a fear of the dark when I was little, but never a monster under my bed, water makes slightly more sense given I developed a fear of a certain pool I swam in with poor lighting conditions, but I always saw fine in it.

Any ideas for what this means? If anything?
