Hi-it happens to me all the time!
The incident of the knife an example. It happens when i'm tired and everything slows down, speech and concentration being the main culprit, or if im concentrating on something else. Its as if the brain is saying 'whoa' one thing at a time. I dont know how you can overcome this -with me its rest and being aware that this will happen. Hope this is of some help-its always good knowing that you arent alone with a problem
