Tsha I believe this happens more in the afternoon, evening. I am not a great sleeper and that may contribute to the problem as well. My husband notices that it is when my thought process is interupted or if I'm say cooking dinner and one of the kids asks a question.

Tonight for example I meant to ask one of the kids to put the dogs out and I was looking for something while I asked and what I said was "put the cabinet in the drawer". My son just looked at me, maybe I was thinking of looking in the drawer next, but in my mind I said "put the dogs out". I'm like what? He said you just told me to put the cabinet in the drawer. I made a joke of it "put the cabinet in the drawer and you didn't get that I wanted you to put the dogs out.?"
