Evil Or Senses?

I'm going to tell you my (continuing) story and I please ask for some assistance. Well, if anyone knows any information about what is going on.

For as long as I can remember I've never been fully able to be in my house by myself. When I was a young child 7 years old I shared a room with my sister and she told me that when she came in late one night (from partying) it was around 3 o' clock in the morning, I had sat straight up in my bed and stared at her. I watched her walk into the bathroom (she walked out the door and into the bathroom) and when she came back in I asked her for a hug and when she said no I lay back down and fell straight back asleep. I know some of you will be skeptical as to was she just saying this but why would she randomly tell me a story of something I did and have no recollection of? She had no need for a prank and my sister is very spiritual as she would not talk about ghosts or spirits unless she had to. I felt kind of creeped out after this, but nothing further continued.

When I was 12 years old, November 1st my brother moved to Australia and I took his room. Let me tell you what that room looks like (you will need for future reference). The door is white and when you step in it is a small box room and when you walk in there is a window directly facing you. My bed makes it so that my feet are against that window but behind my bed is about a 3" gap (three inches and 10 centimeters) where a little ramp goes (for the stairs) then above my bed is shelves and in the corner is a TV. Now from the moment I moved into this room I didn't like it. It had an eerie feel and the room was always colder than the rest of my house even though it was no different to any other room.

My first night there I got barely any sleep as I could feel a presence in the gap behind my bed (the gap is behind where my head goes) and even though I had a pillow there to block anyone/thing staring at me I still felt eyes boring into the back of my head. I continued to feel this every night the eerie feeling of someone watching me, and I never felt safe in my room until I climbed into my bed. I always felt a presence in my room, but never actually in my bed just around it.

A month later (December), I felt the presence getting stronger and I got more tired and weary. I had a chalkboard in my room at the end of my bed and about 3 am on the 13th of December it just crashed to the floor even though it was held heavily against the wall. That day of December 13th I decided to pray. I am fully Christian, so I decided to pray and see if it would help. I sat on my bed and began to pray to our Lord to save me when I felt a pain in my leg (nobody was home and I have no pets) and there was a scrape down my ankle. I got straight up and ran downstairs where I sat on the couch and I began to pray again when I felt a bang in my chest and was winded for a few seconds.

I have never actually seen anything. I can only feel things that are there. I have a shed in my back garden and sometimes when its late I can see a light glow in the window even though there is nothing there.

Halloween the year later and I was sitting on my couch and in the kitchen there was 2 loud bangs (I was home alone) followed by a loud scratching sound against the wall in front of my couch, naturally I was a bit shaken up about it.

I do sometimes see entities but not in my house. In my friends house, for example, she went to the bathroom and I could see a black silhouette of a person just facing me. It had no features and when my friend came back in it was gone.

Recently I got a new dog and it would sit in front of the couch and put his paws on the couch and bark at the space behind the couch. He would sometimes lunge at it for about 10 minutes then stop. There is nothing there and we know he wasn't barking at us as there was nobody sitting on that side of the couch.

I had a sleepover for my birthday (recently) and they had complained about hearing people walking in the kitchen even though nobody went in there and my parents would never get up without telling us they are there.

I would never try to contact spirits as I know that could be dangerous but I am getting desperate. I have tried lighting a white candle and telling spirits to go away but before I can talk the candle just blows out (without any wind).

If there is anything you would like to know and if you feel you can help me please comment below thanks - Rebecca
