Yes I think that some people don't have creative things, but I know that flying is on my list, just because it is something I wouldn't be able to do in the waking world, so it would be an opportunity to experience it.

-Eat lie flavored cake and describe it when you wake up

-Create an epic building in Minecraft and attempt to recreate it in the waking world

-Turn a driving game in to a First Person Shooter/Zombie Apocalyptic game

-Play the Skyrim storyline (or some of it) not as the dragon born, but actually Alduin

-Make someone that annoys you or a random DC get stuck in an endless portal thing (Like in portal) and leave them there XD. Oh, and toss some lie-flavored cake in there with them and ask them how it tastes.

I'm sure I can come up with some better ideas if I think about it
