Oh it was definately your dad. He wanted you to know he's Ok and he loves you. He needed to see you just as much as you needed to see him. you can say it was his way of good-bye, but not gone. Who knows, he may come to you again sometime. My dad still comes to me in my dreams, though it's usually when I've done something bad..hmm, imagine that..LOL, Just remember he will always be with you, rather you see him or not. Remeber that hug...
