Is This Sonar?

All my life I have been experiencing things that I know are not normal. I've been looking for answers, seen doctors, looked online, had my mom's psychic friend tell me I'm an "indigo" and a whole lot of other stuff.

The best way I can explain it is that I feel the presence of the dead. It's almost like an animal's sonar. I feel the shape of whoever it is. Sometimes I can even see the person, depending on how I'm feeling, or get really personal details about the person like how old they are, if they have kids, etc. I've seen my grandfather six times since he died 5 years ago.

I see things like dark shadows that move quickly around the room and disappear. I feel like they are watching me. It's scary. I feel extreme temperature changes in rooms with closed doors and windows, and I know somebody is there. I just know.

I finally confided in my mom about three years ago and she wasn't surprised. She called my aunt who apparently used to have a lot of the same things happen, who called my nana. When I went to my nana's house she told me that at a really young age (like, between 2-6) my aunt and my dad used to talk without saying anything, or my dad would talk for my aunt. The only reason she figured it out was because they would be in different rooms and my dad would come tell my nana when my aunt's diaper needed to be changed, when she wanted a snack, what she was doing when he wouldn't have known because he was playing outside, etc.

I also know things before they happen when it comes to deaths. For example, I knew my grandfather was going to die. I woke up in the morning, went into my mom's room and said I wasn't going to school because Papa was going to die today. He was sick with cancer, but the doctors had given him 4-6 months. My mother was shocked and told me to go to school, but at about 9:30 the class phone rang and before my teacher even answered it I was packing up my books. He was gone and my mom was driving to the school to get my sister and I within minutes.

I also knew my neighbor was dead. One night I just woke up, and thought she was dead. The next day I found out she had a heart attack while visiting a friend a couple hours away.

These things happen to me on a daily basis, and while I have one friend who believes me because he goes through similar experiences, I just feel alone. I just want someone to understand what it's like.
