Naked trees, especially in the fog, make me think of nervous systems. They are kind of creepy looking if you think of it that way. The roots could be nerves too, though we don’t see them. Branches are kind of like air-roots. The tree we see above ground is a mirror of the roots below…
A tree is kind of just a bundle of tentacles reaching out in every direction for food…

I’ve often thought that too…there is something incredibly beautiful about the bare branches. Especially when they have a fine layer of frost or snow.
