When I was younger, about nine years old (I think), I had my own bedroom with a walk-in closet. My bed was directly across from the closet door, so I could easily see inside the closet when sitting or laying on my bed. Normally I didn't leave the closet door open at night because, when I did, things in my room would get knocked over or moved around. Now when I say moved around, I don't mean just scooched over an inch. I mean moved around as in moved to a different shelf on the bookshelf.
Now, it's important to note here that I have no undeniable proof that it wasn't a family member moving my things around. However, when someone did enter my room and touched any of my things, I could feel it as soon as I walked into my room. I literally walked in through the door one day and immediately knew that my sister had been in there and had taken something (I found out later that it was a necklace). That being said, I'm pretty sure it wasn't a family member moving things around. Just wanted to clarify that really quickly.
One night, I was trying to get to sleep. I wasn't very tired but I knew I had school in the morning and needed to sleep. On this night, for some reason, I left the closet door open. After a few fruitless hours of attempting to sleep, I looked over at the closet. Standing in the doorway was a woman. She was completely white (including her outline, which was just a more dull shade of white), and she was looking at my bedroom door. She was very elegant looking. She had long hair pulled back into a fancy, graceful bun (I'm not sure why, but I got the impression that it would have been brown hair had she been in color). Her gown was a long evening gown with bubble like poofs (for lack of a better word) for straps that covered only her shoulders. At first I thought that my eyes were just playing tricks on me. I blinked a few times and she was still there. So I turned over on my other side to face away from the closet. When I turned back over a couple minutes later, she was still there. I watched her for a moment, then turned away again. When I turned over on my other side to face the closet again, she was gone.
She didn't seem to notice me the entire time she was there. She just kept staring at my bedroom door. To this day I still kick myself for not trying to make contact of some kind with her. It's not that I was scared, because I really didn't get any sort of negative vibe from her. It's that, for whatever reason, the thought just didn't occur to me. I'd always been fascinated by ghosts and spirits as a kid, and I can honestly say that I still am. I'm not sure exactly what that lady was there for. The thought had crossed my mind that she could have been waiting for someone to come into the room. Or she could have been keeping someone out, if she had the energy to. I've heard several stories about ladies in white. Some stories say they are death omens. Some stories say they are guardians. Some stories say they are hitch hikers who disappear or kill people. I don't think she was there as a death omen, because nobody that I knew died after that. Other than that thought, I really don't know what she was there for. It was definitely an interesting experience.
