What are some of the more mature dreams you have seen?

There was a level called the adventures of gumbo or something similar which was a simple animation. The mature subject matter came from a kid “gumbo” being asked what he would make and it cuts to him thing of bouncing boobs. The level was taken down pretty much within a day and reuploaded without that part of the animation.

Anyone seen any grim type stuff? I had ideas on using it in horror when/if necessary.
