Sleeping beauty Preity Zinta is busy with late night shooting since last week. She needs a long nap and some dream time too. "Look at me. Don't I look like I need a full-day sleep? I 've been shooting nights for the past one week and what's worse is that there's construction work going on in my building. So, when I get to bed in the morning, these workers star hammering around the place, and my sleep goes for a toss. It's so frustrating", she express.
