The world's a terrifying place, made only more terrifying by everyone's various debilitating, often irrational fears. Find out which phobias affect you by scrolling through the list below. If you're terrified, well, at least you'll have identified your problem.
1. Here's one you already know: arachnophobia. The fear of spiders.
This seems like it's one spider, but it's not. There is one momma spider. The sparkly bits are eyes. Thousands of baby spider eyes.

This is a four-acre water treatment plant that was infested by an estimated 107 MILLION spiders.
Finally, this video features Harvestmen/Daddy Long Legs, which are not technically spiders. That probably won't make you feel any better.
2. You made it...to thalassophobia: the fear of the sea.
Fearing the sea is wise. Because there are things in the sea.

Things mankind was not meant to see. Like this bigfin squid.
Go home, human. You're not wanted here.
3. Ok, why don't we come up for air. Way, way, way up to Acrophobia: the fear of heights.
Oh god no.
No, no, no.
Noooooooooooooohgod I thought we were over thalassophobia!

4. Here we are at number four: tetraphobia—fear of the number four.
In Mandarin and Cantonese, the word for number four sounds similar to the word for death. 14 sounds like "certain death" and 24 like "easy death."
5. Ok, ok. You probably don't have this one. Trypophobia: the fear of clustered holes (aka the phobia no one knew existed before the Internet).
If you think the next video is cool and not terrifying, you might be a herpetologist—which means you hopefully don't fear snakes and you definitely don't have trypophobia. If it creeps you out, well...
It can also be triggered by spongy foods, or bread with a lot of air holes.
The most popular image is this hand with latex makeup on it, which was apparently designed for the sole purpose of bothering trypophobics. (The other stuff is all photoshopped.)
6. Let's examine something a bit more amusing. Coulrophobia: the fear of clowns.
It was a bad day for coulrophobics in this British town when a scary clown kept popping up out of nowhere.
Or in Chicago, when a clown kept breaking into a cemetery.
If you really don't have this phobia, prove it by hiring this clown for your kid's birthday party.
7. Want to get away from Wrinkles the Clown? If you have agyrophobia, you won't even be able to cross the street to safety.
But an irrational fear of crossing streets or highways isn't always irrational.
If you don't get hit by a truck, what if the road just collapses underneath you, like it did in California last March?
It doesn't even help to look both ways.
8. Ok so you're feeling tough because you survived a trip across the road. Big deal. What about astraphobia, the fear of thunder and lightning?
This guy doesn't have it—well, maybe he does now (warning: the video gets loud and profane).
Nothing to worry about, because "lightning doesn't strike the same place twice?" So wrong.
This guy got hit by lightning in the morning and uploaded the video to YouTube in the afternoon.
9. Bravo if you've made it this far. Here's your final challenge—opthalmophobia, the fear of being stared at.
Can you handle the impossibly persistent gaze of this preteen? Dare you to watch it all.
Picture yourself in a hall of portraits with all the eyes watching. There is no happy ending.
Okay, well how does the trailer for the horror movie It Follows treat you? Keep in mind some invisible demon is watching her the entire time.
If you made it this far, clearly you are impervious to fear. Congratulations on your future world domination.
