Shuttles and cannons and leaping grandmothers

Dream one:
I'm in a car speeding along an busy interstate highway. Bright daylight. I'm not sure if I'm driving or riding. I hear something on the roof and look out the window to my left. I see a thin naked elderly woman with short gray hair, a spry grandmother type, leaping from the top of my car to the top of the car in the next lane. It is apparent that she's surfing her way down the road by jumping from one car to another. There is a manic grin on her face.

I arrive at what seems to be an open market area. I'm standing in the middle of it and now I'm without clothes. There are many people all around, but the area is so large that no one is very close by. I have considerable anxiety about being naked and I try to puzzle out how this has happened and what I could do about it. I think that I must have left my clothes in the hotel room which is at one side of the plaza. I struggle with recalling what happened and how I can get back into the room which I believe to be locked.

Overhead, in the very blue sky, a small white plane flies erratically by. It is almost fluttering, more like a moth than a bird, and it is unusually delicate in structure. Someone says that it is the precursor (the trailing flight?) to the shuttle launch, and it's appearance means that the shuttle is about to go up. I look down at the far horizon where I see an enormous gridwork platform, which I understand to be the shuttle launching platform. From this distance I can't see the shuttle, but something there explodes and a large dark smoke cloud rises from the platform. The shuttle has exploded on takeoff.


Dream Two:
I'm in a castle that is a historical artifact of some kind, the sort of thing that tourists would visit. I'm on the top. There is a street that cuts through the castle, and on the other side I see large open doorways and other people. For some reason they want me to shoot a cannon ball in that direction. I aim the small cannon that is nearby and they frantically indicate that I should aim at the doorway, so that the shot will fall on the cobblestones below it and not hurt anyone. I shoot the cannon but the cannonball falls a few feet short. However, there are other cannons and other doorways, and I proceed to aim those other guns in their direction and fire off rounds.
