My worst wake-up experience to date has been to a clock-radio that was set to the oldies station and a Janis Joplin song (I believe “Take another piece of my heart”) was blasting. I had to peel myself off the ceiling after that one.
My brother once woke up covered in vomit and he didn’t know if it was his or someone else’s. EWWWWW!
From the above choices I’m going to choose D.
Anything that involves waking up before noon is the worst way to wake up 
I gradually reach a fuzzy awareness. I yawn and begin to stretch my arms. I can’t. Suddenly, I’m awake and terrified. I can feel satin and wood all around me. I’m in a coffin! Desperately, I search for a handle or hinge or some mechanism to open the lid. There is none. Panicking, I brace both hands against the lid and shove.
It swings open with such ease that it hits the far end of its arc, rebounds, and slams shut again. Gently, I open the lid and sit up. Memory and full consciousness return. I was at a club last night and two Goth chicks took me home. Yes, it’s all clear now. Some jerks were trying to get them to make out for their amusement. I delivered an impassioned speech on how lesbians are people and not a circus act and that they have no sexual interest in men. After several minutes, the jerks slunk out of the club and I received a round of applause. It was at that point that Misery informed me that she and Helina were in fact bisexual. The rest of that night can not be detailed in an SDMB post.
“Oh yeah? Wanna go Camping?!?”
" on the operating table, alert–but paralyzed–under anesthesia" It’s happened.
During Oral Sugery #2 (out of 6) I woke up in the middle of it for a couple minutes. Considering I wasn’t fully put to sleep during the Oral Sugery #1 (where everything went wrong, while I was fully aware of what was happening, the doctor had to call for a second opinion, the equivelent of “oops I messed up”) But when I woke up I was still rather drugged, it was bad, nothing compared to the first time- and he just saw I was awake and put me back under. But #1 still haunts me.

I recently had surgery and they have been starting to give patients a drug that gives you short term amnesia. I was given that first and apparantly I was conscious for a bit before I was completely knocked out. The surgeon said I spoke to him and I have no recollection of seeing him before going under. It was an interesting experience. I could be wrong, but after the surgery I think I was ‘awake’ before I was conscious. I was in a recovery room with a bumpkin and I remember he was in the middle of a sentence about IU basketball, and I had the impression that we had been talking. So what I am trying to say is, it could still happen, but at least you won’t remember it. Bah.

I would choose D.
If not “D,” then I’d say “F”…“Hanging Upside Down.”
I mean, really…could any good possibly come from waking up like that?
Surely the worst way to wake up would be all 4 of these at the same time.
