Seeing Shadows, Silhouette And Faces

This is regarding my experience that often takes place after waking up to bed. It's kind of strange seeing moving silhouette that mostly vanishes after 30 secs. It appears on wall, creeping on the top corner of the room and due its dark characteristic it doesn't have a face or can't seem to have a face. However, the creepiest part is that I often experienced it between 2:45 AM and 3:15 AM. In addition to that, I could also see faces on the trees (only at night) sometimes their faces and bodies looks tormented and grotesque. Is this something that really has to do with powers, ability or any kind of satanic manifestation over me? I'm just wondering what it is all about. Ohhhh and there are some places were I could also be able to feel the heaviness of the surrounding. Is that some kind of a warning? Etc. But still in accordance with these experiences I'd still love to sleep with my lamp turned off. I feel better when I'm alone (optional) when it's dark. I'm hoping everyone from this site could share their experiences and suggestions to what I'm experiencing. I had experience before (once) It was my first time seeing bizarre things. I don't know how to tell everything (long story) but it was like a movie. So fascinating but creepy. In the middle of the woods I saw a tall silhouette of man with a very long legs. Well, it wasn't really a man but it somehow looked like a walking tall tree and a baby figure sticking on root of the tree (it was like an engraved figure of a baby) near the root of the tree.
