Close your eyes for a second and imagine you're at a theme park - Disney World, Universal, Six Flags, whichever you prefer.

Okay, what comes to mind? Exhilarating rides, big smiles, sunny days, salty yet delicious oversized foods, and staff dressed up in all kinds of recognizable cartoon characters outfits, right? Overall, a rather enjoyable time for most people.

Well, forget all of that, because what you're about to see will change your perception of amusement parks for good, even send a shiver or two down your spine.

With eerie, abandoned roller coasters, nuclear-zapped bumper cars, and haunting 'interactive' horror experiences, buckle up for a ride that can only be described as disturbing.

These photos snapped at theme parks are disturbing, so visit the actual places at your own risk.

20 Couldn't even be paid to explore this place

There's nothing more menacing than coming face to face with a sharp-toothed demon, let alone physically setting foot inside its comically large skull. Over in Florida (honestly, are you actually surprised that this is where we've ended up?), this long-forgotten theme park is the Miracle Strip in Panama City.

19 A gloomy, underground Disney city

The entire Disney brand, including its films, characters and various parks scattered around the globe are (or at least, try to be) the epitome of joy and magic. With that in mind, it's a little disturbing to realise that deep underneath the surface of the so-called Happiest Place on Earth is a bleak, bland, dusty underground city.

18 The blackout experience

Is anyone else getting major flashbacks to the scene in The Ring where the demonic girl climbs out of the TV? We are, that's for sure. Located out in San Francisco, The Blackout Experience is designed to scare your socks off, playing on underlying psychological worries and the fear of the unknown. Uh, no thank you.

17 Formerly open, forever creepy

What was once a thriving amusement park that welcomed guests from near and far is now nothing more than an ominous vista with an overly creepy atmosphere. Useful nowadays merely to photographers and explorers looking to see something unusual, the Gulliver's Kingdom park in Japan is officially abandoned.

16 Amusement is no match for a nuclear site...

Unless you've been living under a rock for the better part of the 40 years, you'll have heard of the tragic, ultimately mysterious case of Chernobyl (or at least have watched the TV series, right?). Since 1986 when the nuclear reactor at the Chernobyl Nuclear Power Plant burst, this nearby theme park has been left to rot.

15 ... and winter doesn't make it any less scary

If you thought that the forgotten bumper cars were a little uncomfortable to witness, at least they were surrounded by signs of life. In this photo, on the other hand, the Pripyat Amusement Park in Ukraine looks like nothing more than a scene from a horror movie, with attackers ready to leap out at any moment.

14 A lifeless Tin Man

At the time of its cinematic release back in 1939, The Wizard of OZ established itself as one of the greatest and most enjoyable films ever made, largely maintaining that moniker and the decades flew by. Its theme park over in North Carolina, however, lacks imagination, overflowing instead with rust and uneasiness.

13 The trees are watching

Without leaving the mysterious and creepy Land of Oz amusement park in North Carolina, let's take a look at the strange attempt to create a lifelike atmosphere amongst nature. While the idea of interacting with trees and wildlife seems imaginative and cute, the execution is far from it.

12 Nightmare In Budapest

To call the Nightmare in Budapest a unique experience would be one of the greatest understatements we'd hear today. It's one of those so-called 'interactive' horror showcases, where over-the-top creepy settings are flooded with shriek-inducing actors slathered in frightful makeup. If this shot is anything to go by, we'll be steering well clear.

11 A school we'd never enroll in

Next up, we're heading over to Ohio to find the blood-curdling Dent Schoolhouse. Why is it that a school - a place of learning and fun - can be so easily turned into a house of terror when the lights go down? Not only are the visuals creepy but the actors who dress up as janitors will scare the bejeesus out of you too.

10 Cartoons are ruined when characters lose their heads...

Once again, we're taking a peek into the supposedly magical world of Disney, where, as you can see, everything isn't quite as it seems on the surface. Within the eerie, underground city, actors have old, decrepit lockers that are far from magical. On top of that, seeing a character without its head can ruin childhoods.

9 The most intimidating ducks in the (Okpo) land

In 1999, Okpo Land, a theme park located over in Okpo-dong in South Korea, closed its doors for good. Despite significant popularity for a number of years, its once-loved rides were simply left to collect rust in the harsh elements. The duck ride, in particular, should send an extra shiver down your spine - it sent two unfortunate riders to their graves.

8 Anyone else hungry?

Down at Universal Studios in Osaka, Japan, the park operators have constructed what they call the 'Attack on Titan' ride. In a rather disturbing experience, guests who are game enough can witness first-hand the feeling of being trapped inside the enormous jaws of a Titan - saliva and artificial chompers included.

7 Ain't no water anywhere near these slides

In yet another case of abandoned American amusement parks, welcome to the long-forgotten Wild Waters water park in Silver Springs, Florida. In what looks like a sinister, post-apocalyptic attempt of creating a fun environment, this park is well and truly out of bounds from the public.

6 ... and even less near these ones

While we're on the theme of water parks lacking the one thing that they actually need to survive (that'd be water, in case you missed it), let's jump over to Ebenezer Floppen Slopper’s Wonderful Water Slides in Oakbrook Terrace, Illinois. Unfortunately, it's tough to slide down fallen leaves, so we're gonna pass.

5 An outdated, controversial theme

Even if, hypothetically, the rides behind this Aztec Kingdom facade were the fastest, most exhilarating on the planet, even free of charge, we'd still take one look at it and feel uncomfortable. In this day and age of political correctness, the American Adventure theme park in England just doesn't live up to the expected standard.

4 The unintentional water park

As we look from afar, this could easily appear as a water park - perhaps a new style of water park that's actually built on the water. Look a little closer, however, and the realisation is a little harsh. Sadly, the Six Flags park in New Orleans, Louisiana suffered greatly at the hands of Mother Nature.

3 Not the friendliest of animatronics

Next stop: Japan. This haunting image of a slowly deteriorating animatronic human was snapped up over at the "Western Village" amusement park, located just a few hours north of Tokyo. As you can see, it's been left to sit in its own dust for far too long - at least, far longer than we're comfortable with.

2 The Magic Isn't What It Seems

This image presents itself as disturbing in a different manner to what we've seen in the majority of this rundown so far. Back in 2008, while protesting for increases in wages, a whopping 32 Disney hotel employees - or should we say, former employees - were arrested. Worse of all, some of them were still in costume.

1 Disturbing Disney, calorie version

Alright, we're hopping back over in Disneyland one last time. What's known as the Happiest Place on Earth might be deserving of another nickname - The Most Artery-Clogging Place on Earth. Over 1.6 million turkey legs are consumed at Disney World every year, each packing in 1,093 calories, 54 grams of fat, and 15 grams of saturated fat each. Still hungry?
