Horror, when done right, can stay with you forever. Whether it's the slow creep of Nosferatu's shadow down a flight of stairs, the lightning-fast emergence of a chest-burster, or the gentle rap rapping of an Edgar Alan Poe poem, these are moments that can send both pulses and minds racing.
It's not just movies and books that can create true horror, though – games and apps can too.
Yes, your friendly-looking Samsung GALAXY S4 or Note 8.0 is just a few app downloads away from offering up the ultimate scare factor. If you're of a nervous disposition, look away now.
Here we list the apps and games that will give you a truly terrifying experience this coming Halloween. So, switch off the lights, find yourself a cushion to hide behind and turn up the volume…
Although the plot may slip into cliché at times – you start off in an abandoned house and have to search each room for valuables – play Eyes for a while and you will be immersed in a lovely slab of haunted horror.
It's all in the first person and the 3D graphics are impressive for a free game, so keep your wits about you because there are more than a few scares around each corner. And don't forget that the walls have eyes. Lots of eyes.
A decent first-person shooter game on Android is hard to find. One that can scare you rigid is even rarer, which is why Dead Trigger is such a gem of a game.
Near console-quality graphics that sparkle on the GALAXY S4 or Note 8.0, alongside furious gameplay that never lets up, Dead Trigger offers a sublime horror experience. It will also equip you with all the knowledge you'll need if the world is ever overrun with zombie hordes, which is nice.
If you are a fan of Bioshock's eery steampunk dystopia, then Dark Meadow: The Pact is for you. Given a similar setting, the first-person shooter sets out to shock almost immediately.
The game allows you to get acquainted to the easy on-board controls then… bang! You are hit with your first monster. This isn't a game for the faint of heart, but it is great for those who love shocks and scares, quality graphics and who don't mind giving up a whopping 1GB of onboard storage to make way for this expansive game.
To be honest, despite its name, we don't think you would manage to stomach much popcorn while using Popcorn Horror. This app is the gateway to a wide selection of horror shorts that you can watch for free on your GALAXY Note 8.0 or S4.
Don't expect premium movies here – Popcorn Horror is all about user-generated content. While the thought of this is often enough to fill anyone with dread, don't panic: this app is packed with well-scripted horror and grindhouse movies that manage to instill just as much terror as the latest box-office slasher. Couple this with a creepy community and what you get is a fantastic fear-filled app.
Ah, Murder Room. With a name like that, we reckon you may be able to guess what sort of game lies in store. Yup, this app is set in a room where a murder takes place – and a rather grizzly one at that.
It's made by Japanese horror game studio Ateam Inc and is full of the sort of ghostly goings on that 'J-Horror' moviemakers are well known for. At its diseased heart, Murder Room is a typical 'room escape' game – but this one comes complete with added scare factor.
We all know the folklore: if you say "Bloody Mary" several times into a mirror, the spirit of a young woman is said to appear, and carnage can often ensue. Personally, we think this only happens to people who have had too many Bloody Marys, but this game takes that idea and adds a nice bit of augmented reality.
Instead of a mirror, you hold your handset up to your surrounding area, use your GALAXY Note 8.0 camera technology and see if Bloody Mary is to be found. It's all good scary fun, even if the ending of the game doesn't quite live up to its jump-ridden beginning.
What's black and white and red all over? Believe it or not, that's not the start of an awful joke, but actually a decent description of The Abandoned School.
Melding black-and-white imagery that any cinematographer would be proud of with all sorts of ghostly gameplay, The Abandoned School is a brilliant example of how to bring point-and-click puzzlers kicking and screaming (mostly screaming) into the 21st century.
If you are the sort of person who thinks horror begins and ends with The Exorcist, then the Best Horror Movie Database will be something of an eye-opener for you. Packed with thousands of horror movies and links to where you can find them online, this is a must-have app for anyone who wants to dip their severed toes into the genre, or those who already class themselves as aficionados.
We'll admit that this does seem to be the only horror movie database available for Android, so the name of this app is a little misleading but, hey, we suppose that does make it the best of the one available, and it certainly delivers everything it promises.
We'll admit it – when we mentioned Bloody Mary earlier, we may have looked her up with this creepy compendium of urban legends. She joins hundreds of other 'legends' to make up this collection.
Some of them are unbelievably freaky – the church of carnage is one story that will stay with us for a long time – and some of them are, well, a little light on terror. Sorry, but we are never going to get scared about ice cream.
All of the urban legends are presented as mini stories, so you'll certainly get a decent amount of use from this simple but suspenseful app.
