Have you ever had one of those moments when you are reading something and in one part of your brain it is being understood and you are continuing to read like normal, but the other part of your brain is having a hard time registering what you just read because surely you misread a word that would have changed the whole meaning of the sentence? I find that it usually happens to me when I am reading something that catches me so off guard with its information that I have to read it about 3 or 4 more times to really digest what is being stated.
