Often! Only yesterday I spotted another one and thought to make a post of it! Because for me it was a great way to "proove" that each tree has a dryad (spirit). Finally, I could show you I thought to myself. No threat just an encounter with another reality, which can be scary but maybe they are also scared of you.
When I go deep into my own mind, the only thing that scares me is my own thoughts, so they should be scared of me, but I don't think they can understand me fully to realize how dangerous I am for them.
