Alien abduction

Here's the most curious, amusing image of my operation: I felt like I had been abducted by aliens.

They wheel me into a room that looks more like a warehouse than a hospital surgery room, with big machines everywhere. They stretch me out on a long flat metal bed. They put some kind of canvas tent over my head, so I can't see anything, but I can hear three or four of them hovering over me, poking me, all very mysterious. The image that came to my mind was: I've been abducted by aliens.
