I love this Clark he is so sweet!! blush They are both afraid and Clark doesn't want to scare her off, but doesn't know quite what to do.

“Well. There are a number of different interpretations. One is that you put yourself in the role of Clark. You've been pressuring yourself a lot, so you might have been venting your own frustrations at yourself in your dream. The other is that you were bothered by your Luthor encounter – and you mixed the two men up in your mind. And yet another is that you are genuinely worried that Clark might act this way if being together doesn't yield the benefits you think he'd be expecting. Does this make sense to you at all?”
I think it is all the three together. She is afraid of Clark getting tired of her, she is confusing him with Luthor and Lord Kal, and is also afraid she won't be good enough for him.

Clark: What is that?
Lois: It's my word.
Clark: There is no such word.
Lois: Sure there is. Someone's a chump, therefore, he's chumpy.
Clark: Try again.
Lois: Are you challenging me?
Clark: You bet your sweet little chumpy I am.
