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.
It's not a problem. It's the human mind. Meditation is not meant to stop thought. It's meant to help you notice "what is". You have noticed how busy and restless your mind is. That is good. As you get more into your practice again you will notice more moments of stillness also. Just accept where you are at and let go of any expectations for things to be any differently or the way they used to be.
