Can't meditate anymore

I used to meditate daily, about 2 or 3 years ago I stopped. A week ago I decided to start meditating again. I sat down closed my eyes... and suddenly I am halfway through cleaning my dishes. So I try again sit down close my eyes, and I am doing laundry. I don't consciously see myself stopping and starting these chores. I completely space out on what is going on and "come to" doing a chore or task. What is going on? I have never had this problem before, and normally consider myself to be pretty mindful.
