The body is an amazing organism. Put under appropriate stress, it will respond. That's what you're doing. You're not confusing your muscles/body/mind, you're stressing it and your body will adapt (i.e. put on more muscle, learn how to do the exercises better, etc).
I think all of us take a bit of time off here and there, maybe try something different, but it can be hard doing a wholesale shift into something like crossfit for just a week.
Personally, I've found it beneficial to give the body a week off every few months. Usually this corresponds with a business trip, other times I just do light stuff or work on any issues (i.e. sore shoulder). Either way, it's useful to give the body time to heal and provide a mental break.
