My fingers have minds of their own!!!

Warning: this post is very strange, and you may have a different perception of me after you read it. 

Have you ever been typing and all of a sudden you are typing something unintentionally??! This has been happing a lot to me lately. I'll be in the middle of typing and all of a sudden I'll just start typing about something that is on my mind... without me 'telling' my fingers to do so! Or today I was typing in a password and as soon as I got to a single letter that is in a different password, my fingers just started typing away the different password, without my knowledge. I hope this is something that has happened to a few of you, at least. Thinking on it, I bet a good ad could come out of this idea of liberated fingers.
