Its like sleep amnesia.

Emma never really knew how to say the right things at the right time. She was accustomed to long pauses, anxiety attacks and being lost for words. Before going to bed each night, she would ponder over the highlights of the day and try to figure out if what she said was all she meant to say. Ofcourse, this was never true. She always had some 'ifs' or 'buts' to add or disagree with something that she previously agreed to. Being double-minded never helped, nor did being a dreamer. She made do with the fact that she thought herself to sleep everynight. Every morning the previous nights' thinking would just be erased.
