Don't be scared, just step in and experience the peculiar.
For two more nights, the St Paul's Cathedral crypt will be the scene of a labyrinth of dark urges and dandy pretensions.
In Dunedin Fringe Festival production The Dream Collector, actor Craig Storey brings to life Dr Walford Brody, a hypnotist from the late 1800s.
The "well-dressed bad boy'' was the epitome of eccentricity, a forgotten piece of Dunedin history and a master of dream extraction, Storey said.
"He's an opium addict, mystic, entertainer, snake oil salesman, charmer and a very interesting character to inhabit,'' Storey said.
"He likes people maybe a little too much and likes what is in their heads a great deal more.''
In the crypt, the life work of the doctor is discovered, including his collection of other people's dreams.
Co-art director Maggie Covell said the production was a "happening'' - a mix of visual art, dance, theatre and music.
The interactive installations and auditory experiences intertwined dream-scapes and interpreted the subconscious, she said.
"It's a sensory overload.''
Co-art director Jo Little said the audience should expect the unexpected but anticipate experiencing the work of a range of Dunedin musicians and artists.
"There are many things from this event that someone can take away - it's multilayered.''
The R18 restriction was not because of the nature of the content but because the venue was licensed to sell alcohol.
● The Dream Collector is on tonight and tomorrow in the St Paul's Cathedral crypt, starting at 8.30pm.
