Need answers. "Spirits of the forest"

I can't remember much when I was like 6-10 of age but I was always in the forest and just being with nature and just speaking with nature. yet I always saw them clear as day figures in covered in darkness yet white eye, even when I was with friends, only I saw them I would only see 1 or 2 infront of me or standing next to a tree watching me then they would walk behind the tree, vanish. I would only see then in forests or when im near a forest after seeing them when I go home, in bed at night i would sleepwalk or have night terrors. But now I don't have either, I do tend have few weird dreams, like I would fall asleep within a dream and dream inside a dream then go through a process of waking up within those dreams till I'm actually awake they all felt real yet off but beside the dreams, I still see them occasionally when I'm exploring different forest always 1 or 2 watching me from distance never interact with me, just watching. I tried looking for answers to these "watchers" or "spirits of forest" what I call them but I can't find anything. Does anyone know what this is or what it could mean. Please give me answers cause I feel like I'm alone being only one who sees or know of them.
