A school girl suffers from a rare sleeping disorder, which means she snoozes for up to 44 days at a time.
Although it's known as sleeping beauty syndrome, Lois Woods' life is no fairytale as she is also affected by zombie-like trances when she attack herself and her family.
When the teenager is suffering an episode she bashes her head against walls, attacks her young brother and gorges on junk food in nighttime fridge raids. She also suffers Jekyll and Hyde-like personality changes turning her into everything from a babbling toddler to appearing like a violent drunk.

Lios and her family are here to speak more of her story...
