Theatre and dreams have much in common. Both offer an alternate reality and, like the best dreams, the very best theatre makes you believe that what you've seen - and felt - is entirely real.
Alas, it's not the case with this piece written and directed by Mark Murphy, formerly of Vtol Dance Company. In recent years, Murphy has been making a journey away from movement towards text, but this two-hander that examines the mysterious and fragile world of the unconscious lacks mystery and fragility. It is all too obvious, like some arty TV drama, rather than a textured and layered piece of theatre that pierces dark secrets, dreams and nightmares.
Luna suffers from a sleep disorder called parasomnia that makes her act out her nightmares, much to the disquiet of her boyfriend. But her nocturnal wanderings and terrors are becoming more frequent. Could the key to her nightly horrors lie in her childhood and the flight of stairs and closed door she so vividly describes?
By heck, of course it does, because although Murphy's scenario may have a non- linear narrative and a multi-layered soundtrack, it's really a very old-fashioned thriller in which everything leads back to Luna's past and the terrible sight she witnessed behind the door.
Just because you tell your tale in a slightly different way it doesn't make a dull or predictable story more interesting, and Murphy runs out of ways to hold the attention as the story spirals into therapy speak and melodrama.
Catherine Dyson and Jason Thorpe work like the clappers to give life to the entwined stories of Luna and her boyfriend, and Luna's father and therapist. But ultimately this is a bit of a nightmare.
