The Twilight Dimension

After encountering a mysterious building at their school (that wasn't originally there before), a group of 6 teenagers find themselves waking up another dimension (a replica of their school) that is inhabited by entities that can mimic voices every night. They face multiple challenges and life-threatening situations as they try to find the reason for this hellish nightmare and how to escape it.
