Yes, I remember that when I was about 10 or 11 years old, at a sleepover at Susie's house, I was sleeping on a sofa and I had a dream, in which there was a box, and I opened the lid, and the lid flipped open as if by a spring, and the lid hit me on the leg somehow, even though the angle may not seem right, and then I woke up and saw that Susie's brother had come into the room and had thrown a shoe at me, which might not seem very nice, but that is how boys are, and he thought that was funny. So I never got to see what was in the box in my dream because of the shoe.
