I can't say that I have a "dream RP." But I do have moments that I would love, someday, to play out in an RP setting. 

[u]1. "Super Saiyan Moment."[/u]

Basically just wanting to play out a character having a rage/truama-induced burst of power; potentially even a transformation if the setting allows for it or I can otherwise validate it in the context of my CS. 

[u]2. "You saved me from myself."[/u]

I've imagined a few of my characters having scenes like this. They're at the end of their rope, most likely on the edge of escalating aggression/violence to a level that is dangerous for them long term. Think the classic superhero (Batman is a good one for this) ideal where killing a criminal is a line they will never cross. Would love to play out an instance of my own character prepared to pull that "trigger," knowing that once they cross that bridge, they won't be coming back from it; then have it cut into by someone who's character  stays mine's hand. The following scene would see my character looking at my partner's and giving a comment on how that person rescued them from permanently changing the core of who they are.
