Do you ever just skip a whole week in your mind?

I am finding myself becoming mildly disoriented in time and space because I'm skipping over entire week's worth of time because I know that it's all taken up with "stuff" and thus unavailable for getting stuff done. For example, next week there's something or other sitting in the middle of Monday, the office potluck occupying much of Tuesday, no one is going to do anything on Wednesday, then tryptophan-n-football Thursday, followed by finally-take-down-the-Halloween-decorations-and-put-up-luminarias-Friday.

Basically, the whole week is shot.

But then I found myself panicking because I jumped ahead to the week after next in my calendar and looked at what was scheduled there and began conflating the two weeks. Wait, I can't have a meeting with Dr. So-and-So on Monday, that time is all taken. Except it isn't.

I might just be an idiot, though. This possibility has occurred to me.
