I don’t think daydreaming is exclusively a daytime affliction. I think if you are awake, but not all there at the time, you could be considered daydreaming whether it is night or day. You have to wonder sometimes though, if daydreaming begets inspiration, or inspiration begets daydreaming. Either way they both result in the same thing, a dumb mindless look on your face as you drift off into your own little world. Even more embarrassing if you’re on a bus and don’t realize that you are staring at someone during your sabbatical from reality. People tend to think your not right in the head when you sit there staring at them wide eyed with your mouth agape and a thin little bead of drool slowly making it’s way out the corner of your mouth and down your chin.
