Yea extremely complex indeed, there are several things we do without thinking. Practice this with yourself how much of talking is done with a thought in mind first, unless you are mulling over what you need to say in a pause. That isn't always needed right? If getting into dissociation, since this is the dissociative disorder forum you will have moments like that in a normal person. Stick with I don't remember note those times you don't remember. I would say I said something, but I can't say it again because I don't remember. I don't know why it was funny . Stay away from those people that place those demands on you to remember everything.
