Is it normal i have a connection to a dead family member?

My uncle died when my dad was only 9 years old. My uncle was 18 at the time and he died in a car accident. I've always missed him and wished I met him but as I reached my 18th birthday and came closer to getting my licence the connection seemed closer then a few months after getting my licence I went to a group medium... He and his mother were there. I stayed quiet because I was nervous and didn't want to cry in front of all my partners family (I had gone with them) and ever since then it's been even more worse. I try talking to him but get nothing no hints... I feel this ache in my stomach when I miss him and I often cry about his death....
