This Is My Story About Feeling And Seeing Ghost

It all started when I was little, I could hardly understand what was going on with me. I can tell how many ghost are in a room, their age, what they're wearing and how they died. I live in an apartment and I have a five year old boy ghost that's always turning on and off my lights. He plays in my hallway. I can hear and see him laughing and playing with my puppy and my son. The little boy had told me he drown in the bathroom. That he's lost and needs help. He gets mad when no one is home or when we go to bed. Is it normal for my dog to see them as well. He be barking at nothing sometimes. I also can feel my girlfriend's grandma, she sits in my rocking chair talking. She told me things about my girlfriend that she hasn't told me herself. It's kind of weird for me because I get cold chills that no one else gets, my hair stands up on my neck and arms. Sometimes I don't feel right. I would like to know more about what I see and hear. I'm scared to be alone in my house sometimes because I get a feeling of negative energy. I try to ignore it sometimes because it feels bad. My son also experiences the something he started seeing ghost at the age of three. The first ghost he seen was an older man in his fifties with gray hair he died from a heart attack in the trailer we were renting. My son won't sleep by himself for awhile. I tried to explain to him that it's a six sense and only some people have it. How do we get our six sense were does it come from? I would love to help the ghost with the gift I have but I don't know how. Thanks for reading.
