In 2010, Sonia Vallabh watched her mom, Kamni Vallabh, die in a really horrible way.
First, her mom's memory started to go, then she lost the ability to reason. Sonia says it was like watching someone get unplugged from the world. By the end, it was as if she was stuck between being awake and asleep. She was confused and uncomfortable all the time.
"Even when awake, was she fully or was she really? And when asleep, was she really asleep?" says Sonia.
