Taking place in the same universe of ghastly somnambulance as the first 'Sleepy-Time Time,' this installment chronicles a new collision of several mysterious, nightmarish forces.

Again using sleep paralysis as a point of departure, this second installment in the 'Sleepy-Time Time' series pits our somnambulistic hero against vast, terrifying, undefinable forces which seep into our world through radiators and cracks in the plaster, slavering viciously as they tear into the very fabric of our dreams.

When the Sleeper finds the mirror shard behind the bookshelf, the book that falls into view is "Choose Your Own Adventure #27: The Horror of High Ridge," written by Julius Goodman and published in 1983.

The masks used in the finale were previously used in the play "Aenigma," which debuted in New York City in October 2008. It was written by "Sleepy-Time Time" director Sean Gill and directed by Rachel Klein.

The paperback that the Sleeper is reading at the film's start is "Disco", written by Chelsea Farraday and published in 1978.

Based on director Sean Gill's own horrific, hallucinatory experiences while afflicted with sleep paralysis.
