The occult's return to art: 'Before, you'd have been laughed out of the gallery'

Tantra, spirit mediums, Obeah - why have things become a bit witchy' in the art world of late? Our writer takes a trip into deep space to find out

Last night, Suzanne Treister took me on a 400bn light-year journey into space. The purpose was to visit her Museum of Black Hole Spacetime, and so, along with a couple of dozen fellow travellers, we jetted off - via a seance led by Treister. Describing the shared journey as we rose up from our chairs, through space, to reach her fantastical museum, Treister hoped that we would reach an altered state of consciousness, ready to experience visions" that we might otherwise be unable to experience in our everyday lives".

We drew and described whatever we felt we encountered during 20 minutes in the museum (in my case a monster tree and ersatz Hilma af Klint paintings), before Treister talked us slowly back down to earth.
