ESP double checking

Often after I write something, whether it's an email, forums post, blog post, or something else, I'm thinking about it a few minutes later and feel like I probably made a mistake in or near one particular sentence. So, I go back and reread it. Often it's nothing, but often enough I actually did make some mistake in my wording around where I thought I did. It's a very subconscious thing; I don't know why I feel like I made a mistake there, or even necessarily much about what that sentence was. I just have a gut feeling that I made a mistake with the last sentence of the second paragraph. I guess "subconscious" is a valid word for that. After writing, I sometimes have intuitive feelings that point me to errors I didn't realize were present when the text was written. I really have no idea if this is something that most other people experience too.
