Abandoned Hospital Awakening

An Abandoned Hospital Awakening is, as the name implies, when a character wakes up in an Abandoned Hospital. A combination of several different things in a single convenient package, an abandoned hospital awakening is a popular choice for beginning Horror works, though it shows up in other genres and contexts as well. The hospital used for this has usually been recently abandoned after a disaster of some sort, which helps explain why the character was there in the first place (though not necessarily why they were left behind).

Abandoned hospitals are creepy, which sets the tone by itself, but the addition of specific types of Scenery Gorn can ratchet that tension up even further. At the same time, it gives the characters (and the audience) a clue as to why the hospital was abandoned in the first place. Being in a Convenient Coma while the disaster was happening gives them an excuse to be Late to the Party, making them a Naive Newcomer until they figure things out. If they don't remember why they were in the hospital in the first place, then you've got an Ontological Mystery on your hands in addition to dealing with more immediate problems.

Especially popular during a Zombie Apocalypse, for some reason. See Abandoned Hospital for the supertrope. See Waking Up Elsewhere in general.

Examples of Abandoned Hospital Awakening include:

Comics

The Walking Dead opens with Rick being shot, then cuts to him awakening some time after the Zombie Apocalypse has begun.

Film

Twenty Eight Days Later opens this way, with the protagonist coming out of a Convenient Coma twenty-eight days after the Zombie Apocalypse erupted in London.
The Descent subverts this when Sarah seems to wake up in an abandoned hospital after her car crash, but she turns out to be hallucinating.
The first Resident Evil movie uses this at the end; Alice wakes up in a Raccoon City hospital, with the Zombie Apocalypse well underway outside. The same scene also comprises the beginning of the second movie, Resident Evil Apocalypse.
The Lost Tales from Camp Blood short included with the Friday the 13 th: The Final Chapter Deluxe Edition.
The hospital Nightmare Sequence at the beginning of Rob Zombie's Halloween II.

Literature

John Wyndham's The Day of the Triffids opens with the protagonist waking up in hospital following eye surgery, his eyes still bandaged. This turns out to be just as well since everyone else has gone blind from looking at weird lights in the sky, and now the population is being picked off by ambulatory, carnivorous plants.

Live Action TV

Like the Comic Book above, The Walking Dead does this with Rick at the beginning, though the first scene shows him getting shot during a traffic stop, to explain what put him in the hospital.

Music

The beginning of the "Party Rock Anthem" music video.

Video Games

Variation: the main character of Shin Megami Tensei Nocturne awakens to his power in an abandoned hospital. Why is the hospital abandoned? Because a doomsday cult have taken over it. How does he awaken? By being injected with a demonic insect (through the eye!) by that Lucifer. Try counting how many horrors there are in this example.
