Increased Appearances

Let me just start off with these experiences. And I don't know what to make of this so any help, comment, explanation, anything will be much appreciated!

So I was watching TV at about 23. 30 hours and just laying down and relaxing. My grandma was asleep on the couch and I didn't want to disturb her so I reduced the volume so that it was just audible and I turned off the lights. I was immersed in the programme and it was about 15 minutes later that I felt a warm breeze like feeling over me, it came from the right side, which is and adjoining room. All the windows were shut except one and I shut them myself long before. This breeze enveloped me and it felt strange. Like it was not like an ordinary breeze or anything, it didn't feel like it. I didn't think much of it as I was still engrossed in the programme. After a couple of minutes, I saw a chair in the adjoining room which was just beside the doorway, slowly turn and move backwards. It turned slowly and it felt like forever! It turned by itself. No breeze, nothing. There was no one besides my grandma who was sleeping, in the house. This freaked me out and I was scared for some reason. It wasn't major but I was still scared. My grandma awoke after some time and I told her about it, she was genuinely worried. She sprinkled blessed water around the house and also on me.

But after that incident, I have always felt like there was something watching me, always in that room. I once saw something sitting in the corner of my bed while I was in bed. It looked very vague, I couldn't see its features or anything, but it looked like a distorted version of a human and it was severely thin- like it looked bony and malnourished and it had this sort of greyish black appearance. It just stared at me and I kept looking at it. Nothing happened and it disappeared. Also after that, some months later, I have felt an increase in this feeling of being watched. I couldn't see it but I could definitely feel it, even when others were in the room or house.

And in the past month or so I have repeatedly been seeing some shadow or sometimes an apparition like thing in my house, I only see it in this part and nowhere else. It just looks at me and its hands are by its side and it just stares. I mostly try to ignore it but it does give me cold chills nowadays, and when I look at it again and again, it's still there. It leaves after about 2-3 minutes. I must note however that I see this being or apparition only during the evenings or nights. And it has a greyish black appearance as well and just this sort of aura like thing and its very disturbing. It has not done anything but has merely been making appearances. So I don't think it means any harm but I would still like some answers, please. Also, when I look at some things, a jacket sleeve for example, it seems to be moving- twisting and turning and the like but when I turn away and look at it again, it looks untouched. Please tell me if I am losing my mind or if this is actually something that others experience.

The house is my grandparents' and was passed on from the previous generation. They lived here for like forever. Before it used to serve as quarters to British soldiers' families. Just in case it will help.

I hope someone can help me.
