I'm not sure if I have or not. It's really strange actually. I remember in great detail riding in the back seat of the car when I was probably 4 or 5 years old, and I lean my head back to look out of the backseat window to see a huge UFO. I can remember the family stopping at a gas station and everything, however nobody else remembers this. It could be a dream, but it is as vivid as a memory and I've had it my whole life.
