Nothing as spooky as yours, but I didn't want to read and run 🙂
Many years ago when I was in my early 20s, I went and stayed with my friend and her partner. There was also a friend of her partner staying who ( as my grandmother would have said) 'had his eye on me'.
I was lying on my mattress in the lounge and nearly asleep, the door into the hallway was sightly ajar, and there was a light on somewhere so the hall was slightly lit. A silhouette appeared in the doorway and moved into the lounge/my bedroom and stood beside the wall. I assumed it was this fella, so told him to get back to his bed. The shadow then just faded away!
Next day I realised that no one could have stood where 'he' stood as there was a big sofa right there, nor could 'he' have fit through the gap between the door and the door-frame without the door opening further.
