I genuinely have a question as I have been seeing this quite a lot lately, and am new to seeing such a thing. There are times when I am just admiring the beauty of the woods and I will see a shadow "human" figure whether as part of or in front of a tree trunk. These shadow figures have not moved or anything, they are just there. My thought is that they are a spirit of the tree. I am not sure if that is correct. Anyone else ever see this?
