Have you ever participated in a seance?

Someone had been recently murdered, so we decided to hold a seance to figure out the culprit. We managed to get a really dark room, drew a magic circle with salt, got someone to act as the vessel who had to crouch in the middle of the circle inside an iron cage, covered in a white sheet, with a heavy wooden dog statue on top of it. After extinguishing the lights, the room got pitch dark and we sang a song...

But it didnt work. :/

Don't even know what that word means but judging from other replies I'd say I didn't
