shadow dying

I dreamt that I was dying. A few people in my family already had died. It was some strange sickness. It wasn't painful or scary. It just started overtaking your body, like a dark shadow. You pretty much knew when you had it and how much time you had left. My dad had already had it and the shadow had already taken half of my body. The other half of the phase went quicker, so I was telling my brother good bye. I wanted to give him a hug or something symbolic of .. hey this is it... see ya. He was preoccupied. So I figured this was it... on my way out and uneventful. I was a little disappointed... like a major milestone birthday being forgotten.
