Some clichéd dreams for a clichéd guy. :-)
1. MazeJack's lost in a maze of corridors, which at times may look like those of the
Dalek homeworld, Skaro, at others like those of the Game Station where he died his first death, and at others like those of an old hospital where he once ran away from a child in a gas mask. Somewhere ahead of him is Ianto, with Spike dragging him further away, but there's only ever the faintest glimpse of them.
What there are more glimpses of are monsters moving in the dark, hiding behind corners and the bulkheads that are always plentiful in Doctor Who. Daleks, Cybermen, Slitheen, Sontarans, Nostravites, Weevils… and perhaps your character will bring with them some of the monsters from their world too?
2. DyingHe's down beneath the Earth, facing the Blessing, waiting for Gwen to shoot him in the back and spill his blood into it, to end the Miracle and set the world back to how it should be. He braces himself, arms spread wide, ready.
[You can take Gwen's place in shooting him, or try to talk him out of it, or just be there to comfort him when he falls.]
( cut for length and NSFW-ness )((OOC: All of these are open to absolutely anyone, whether we already have CR or not (and if we don't, you can choose whether in the dream they know each other or not). It would also be fun for one dream to shift into another, as dreams do. Also, OOC negotiation is good, especially for the BDSM dreams, but also for anything else you want to plot out too, including completely different scenarios if required. :-) ))
