Can't find the rhythm.

My brain has a little problem. It goes like this.

I read a book in first person present...and then when I go back to my novel words don't sound right anymore! I get confused, things don't make sense. Wording seems awkward.

I just finished up the novel Anna and the French Kiss...which I LOVED! Don't get me wrong, it's not Anna's fault. But all I can hear is 1st/present. The end.

Does anyone else have this problem???? How can I switch my brain back?
