Friendly Trying To Make Contact?

I live in Florida, where I hate and love the place. I hate Florida's weather but I love the people.

My story begins when I was 14. I was in my bedroom when I first saw him. I was doing homework, and I had this feeling that I should look up, so I did. When I saw him, he was just standing there staring at me with a smile. That freaked me out. I started to go into a 'what is happening?' mode. I guess he saw that I was scared, because he vanished right in front of my eyes. I tried to explain this occurrence to myself with logic. I told myself that I was seeing things and should probably get more shuteye. But that wasn't the end.

The next day I came home from school and I was alone. I put my stuff away and went into the living room and sat on my couch and turned on the TV... A couple minutes later, I saw the same guy sitting at my kitchen table, watching the TV as well. Instead of freaking out, I tried to talk to him. I asked, "Who are you?" He turned his head at me and I guess he was speaking, but I couldn't hear him. I said to him, "I can't hear you. Can you hear me?" Which looking at that question now, I feel kind of stupid because he obviously heard me the first time. So in response to that question he nodded his head, and then disappeared. A few seconds later my mom opened the front door. I don't know why, but I only see him when I'm alone.

Every now and then I see him. But every time he tries to talk, I can't hear him. Does anybody know how to help with that problem?

Also I don't only see that guy; I see some other things too. Some of them are creepy but I will share that in other stories.
