My Babysitters a Vampire (2011)

After Ethan, Benny and Sarah all boast about being able to handle their adventures on their own, Benny's Grandma sits them down for a serious talking-to. Something dark and sinister is on the horizon, and to handle it, they'll have to work together as a team. After they brush off Grandma's 'old school' advice, each of them wakes up alone - trapped in their own universe, with only their fears to keep them company. They have to devise a strategy together to break free, and most importantly, escape the fearsome hooded figure watching them from the shadows.
