I do it, and I've actually gotten worse since I've been pregnant!
ME (asleep): What's that?
DH (awake now): Where?
ME: On the wall!
DH: Which wall?
ME: The wall...
DH Turns light on.
ME (now awake): What did you turn on the light for???
Usually its all very inquisitive. What's that noise, what's that, who's there etc!
