Have you experienced paranormal activity?

All my life since I was a child, I've heard things. I was so afraid of the dark that I had to leave a lot of lights on when I was younger. I still leave a light on. When I was 7 I was sleeping in my bed and I kept feeling like I wasn't alone and I was really scared. I kept thinking in my head that I could just run upstairs to my parents room as fast as I can. And then I heard a voice behind me say "Don't even think about it" I've never ran so fast in my life. One time when I was 9 I had a werid feeling about these tall candles we had they sat on top of this high self on the wall, I just had a feeling like they would fall so I pushed them as far as I could against the wall. In the middle of the night I heard a loud bang. I got up to go check and the candles were on the floor broken in half. I used to always hear foot steps and voices, my parents thought I was crazy. Recently a few years ago I was laying in my bed about to go to sleep and I was just on snapchat and I accidentally took a video and when it played it back I heard a voice and I literally died it was so scary. Because I had my flash on on my phone while it was taking the video and the voice said in the video "turn it off" 🙈🙈🙈 I didn't sleep in my room for awhile after that. All my friends and family could hear it too. Then about a year ago This was in daylight I was in my room folding clothes and I heard my dad come down the stairs and was talking on the phone. So I was like oh .. dads home. I didn't see him downstairs so i went upstairs and asked my mom where's dad and she said he's at work! my heart literally sunk. I checked everywhere in the house. I don't know what I was looking for but it just didn't make sense. The werid thing is that my mom is a twin and they both have their own ghost stories. I went to a medium last year and I told him I always feel like someone is watching me and he said well if you feel that then someone probably is. He said some people just have the ability to sense spirits etc.. even my aunt my moms twin has had a medium say she has a gift and they could teach her how to use it if she wanted but she didnt want to lol. And what freaked me out the most is that I had the same birthday as the medium. He also told me that the time I thought my dad was home could of been my grandpa my dad's dad. He gave me some sage so i could sage my house to get rid of any bad spirits or bad energies. You might think i'm crazy but this is all very real to me. Sorry for the long post.
