I will start with mine, mera worst nightmare yeh hai ki mein mere school mein der se reach karti hoon and the school is somewhere in some hill or something where it is impossible to reach and guess what I am in my pajamas on my way to work. The thought scares the hell out of me. Doosra wala mightmare hai ki maine guests ko bulaya hai dinner par and the house is super messy and the dinner is not ready.
