TDK:JESUS! They are making you hallucinate? If they freak you out and you DO get a heart transplant and live a long life you might have Post Traumatic Stress disorder. Tell them to be careful with how much they give you. Doctors make mistakes. And I say you should stay in the hospital. And dude. You aren't screwed. You are going to be okay.
I actually asked them about that, but they said that it was a normal thing. Crazy ***, that David Tennant (He's the current Doctor for those of you who don't know).
and yea, they warned me and my parents that I might get PTS, but I'm not worried. I've got a pretty strong will, so if I pull through, I think I'll be fine.
Relax. You only live twice, you know.
