There are so many reasons this could be happening. You are obviously quite young so I guess its nothing to do with age related forgetfullness. This can happen if you are constantly doing repeated tasks that are really quite boring and hardly need thinking about. It could also be an underactive thyroid. You would need to see a doctor to rule this one out. If it is gradually getting worse then do please see your doctor anyway.
You need to see a doctor about this. You could be having mild seizures. That is what it sounds like to me.
