I Have Incredibly Haunting Nightmares

My character being haunted by Russell Brand is scary enough but my character turning into him? It's even more horrifying and also heartbreaking seeing my character who is a good guy turn into his arch enemy who is in fact evil. By turning into Russell - he's basically going to switch alignments from good to evil and he's going to be just as evil as Russell himself if not worse. If that ever happens to me, either hold me down, try to find a cure or keep me at bay with silver and/or holy water.
