Is He Trying To Tell Me Something?

Ever sense I was little I have been a psychic and I never have gotten used to it. But this was so much scarier. The other day I was outside listening to music from my mom's car. It was two days after my birthday. So anyways I was sitting outside and I was waiting for my mom's friend to pull up in to the driveway when I saw some headlights. I got up to greet him when he got out of the car. But a few minutes before that I heard someone scream and heard a group of people talking to me but I could only hear whispers. But after I saw the headlights I turned around because I heard someone say my name in my ear so I turned around to see who it was and I heard the car turn off. I turned back around to greet him but the car was completely gone. And it was where he usually parks his car when he comes over. And that is all the way up the drive way. But it was gone! My mom is a psychic as well and she has been visited by a young teenager who was killed in a car accident near my house. He told my mom he needed help telling his mother not to be sad over his death that happened awhile back. My mom said she had a visit from him and that second I got a picture of him in my head. I described a young boy about 17, wearing a yellow T-Shirt, about 5,7, and had brown curly hair. When I told my mom this description she was scared. She never believed I was a psychic like her. But now she knows I am. She never told me what he looked like before this. But I just told her the exact way he looked without a problem. Does anyone know what this is? I'll take any help I get. Thanks.
