When I was younger I would see a figure that looked like a monk with black robes. For all but one occasion, it had its hood up and would stand in corners watching me. However, there was one night I saw it without its hood on. It sat on my bed and peered over me before removing its hood. Its face was that of a corpse, and in place of eyes it had dark sockets with a glowing sky blue light. After that it started getting physical and actually scratched me once.
Whatever this was, the spirit I met shortly after I started seeing this thing taught me how to get rid of it, and I haven't seen this being in about seven or eight years since I got rid of it. I am curious to what it was though.
If you have any clue as to what this is, please let me know.
