Two nightmares come to mind, and one of them happened just last night.
One nightmare which has been recurring at some times, is that I am kidnapped, and taken on a plane, and flown up to airline cruising level, say 30,000 or 40,000 feet, and then tossed out, with no parachute. In the dream, I just keep falling, and falling, and falling, and never hit the ground, almost like a free fall. I know that when I've had this nightmare, I've sometimes awakened to find myself clutching the sides of my bed for dear life.
The other one occurred just last night. In this one, I'm trapped in a zoo, in one of the animal cages, and suddenly, a giant panda shows up, and just keeps beating the crap out of me. The panda has me backed up to the wall, and whales on me, hitting me with his paws, and his head. I woke up last night in the middle of the night, and had images of this huge panda in my face. Until last night, I had never given much thought to pandas. Now, I hope I'm not going to be paranoid if I ever go to a zoo and see one.
Those are two that come to mind.
