My dad recently died on election day of last year. I have seen him twice. The first time I knew the reason behind it. It is now that I can't figure out why I am seeing him. I saw him recently in my truck when I was looking at a home with my best friend. He was siting in the passenger side of my truck when I got out.
Can someone help me here with this and even tell me why I am the only one from my family that is seeing him.

Thanks
