I'm outside at night, looking up at the stars. Although I'm in the city, with considerable light pollution, I can clearly discern seven stars of the Pleiades, compared with the five or six I can usually make out under urban conditions. I mention this to my brother, who insists that he can see twelve.
I become aware of a huge wheel-like configuration of stars in the southwest, about 60 degrees of arc in diameter. Individual stars are continually winking in and out of visibility. At first I think the whole thing is rotating, but then I realize that there is a radial segment of greater visibility which is moving around the wheel clockwise like a radar display. When it passes the one o'clock region, it briefly lights up a group of stars that form the shape of a bull's head -- a bit like the Chicago Bulls logo, actually. I think, Oh, that's Taurus; I'm looking at the zodiac. Then I immediately correct myself: Of course you can't see the whole zodiac as a literal wheel in the sky.
As I continue looking at this wheel, what I had thought was a configuration of stars gradually resolves itself into a physical structure -- a gigantic ring, sort of like a "Stanford torus" spacecraft but with no hub or spokes; just a huge empty ring. (The "radar display" effect has ceased.) It appears to be a manmade structure but is impossibly huge, with the bottom nearly reaching the horizon and the top some 60 degrees up.
As I watch, a second craft sails through the center of the ring toward us. It looks exactly like the starship Enterprise except that the propulsion units are angled down rather than up, so that they look like the pontoons of a seaplane. My impression is that it has flown down to the ocean, bounced off its surface like a skipping stone, and then glided through the ring like Mr. J. Henderson through a hogshead of real fire.
"Something just came through that ring," I say to my brother. "I'm not sure if they're friends or enemies."
Not until I typed this up did I realize that a Freud-style pun likely played a role in the dream's sequence of events. Just after I think Taurus, the zodiac resolves itself into a torus.
