You hear a trailer rolling up (zoophilia)

One night, as you dream lucidly, you begin to have the wettest dreams possible. Throughout your usual 8 hour sleep cycle, you begin dreaming about anything you want. You can become a princess captured by horny orcs. A leather clad dominatrix with a varied collection of slaves. A space pirate with a 12 inch cock. Anything your subconscious mind can think up, it can become reality in your dream. Whether it be mundane or bizarre, controllable or uncontrollable, is entirely up to you.
