From the bedroom

It's another morning and Craig wakes up perturbed. His night has been riddled with an odd dream that he can neither decipher nor remember.
Getting out of bed, he decides to go through his usual routine and start his day. Heading into his bathroom, he ends up in a strange room. All attempts to return to the familiar space prove futile.
He figures he's stuck in a labyrinth of strange rooms with no seeming escape route. These rooms slowly become more and more weird, complex, intricate, dangerous and at a point, life threatening. Stuck in this labyrinth, Craig is unable to get out. Is this some dream or did he get lost in an experiment perhaps? Will he ever get out? Alive?
