dreams

I've only had a couple of dreams about my dad since he died. In them I usually don't know that he is gone.
Last night I dreamt we lived in our old house, on our acreage. My little sister was wandering around outside in the dark and I was trying to get her to come back. When she did, my dad was there. I really don't remember a lot after that, except that I gave him a hug and didn't want to let go and told him that I needed him. I think I knew he wasn't staying.
Sometimes I like dreaming about him because it seems so real, but I don't like waking up and remembering that he's not here.
