Book of Dreams - Dream 3: Welcome to Crateland (1994)

In this first of the two Book of Dreams shorts, a puzzled young woman called Mona, who has certain femme fatale qualities to her, retells a surreal dream she recently had. She's lying in her bed in her negligee, when a macabre grinning older man with a gun appears and tells her to enter a crate that appears in the room. With her inside, the crate is placed on a nightmarish assembly line of sorts that carries countless crates with similar cargo to their doom - a boiling pot-like structure. She's not afraid for some reason, but still wants to find a way out before the crate reaches its destination. It turns out that there's an infinite amount of space inside the crate she's in, so she crawls around the crate exploring it. She has a couple of odd encounters there, including one with the grinning man, who reappears to ask her to stay, claiming that all her wishes will come true there, but she isn't buying it.
