Recently had a dream where I was looking in a mirror and noticed I had some weird stuff on my face - a bit like a small patch of moss. As I pulled it off, I noticed some twigs sticking out of my face. Each time I removed these, more would appear. In culminated with a small tree stump which I had to prise off the top of my head.
Throughout, I was a little concerned about pulling stuff off, as I thought it might hurt but it never did - despite these twigs/stump being part of my skin. When I pulled them off, there was healthy skin beneath and no mark left.
