how can I lose my voice overnight?
You yell in your sleep.
I believe if you scream for a long time until your throat gurts, that will probably do.
Someone sneaks into your room and sticks a knife down your throat
do you want to? or did you?You can lose it by squeeling and screaming, I lost mine at a concert, or if you have a virus, that can cause voice loss.
Scream all night ?
Scream. And scream. And scream. And scream. And when you can't scream anymore, keep doing it. Or you could fake it. I know I have faked my fair amount of sick days, hoarse voice, and other things.
