Your Irrational Fear.

[NimbleJack3]

What's the weird thing that you secretly live in dread of? Something that is highly unlikely to happen, but would scare the shit out of you if it did.

Mine is a fear that I'm going to turn the corner and I'll suddenly be in a parallel world where I don't exist. It's stupid, but scary.

What's yours?

Creepy faces begging for help through reflective surfaces. Saw it on X-files when I was a kid, it has left me forever scarred.

I'm afraid of lots of money and fame, and what it could make me do. See recent tiger woods episode of South Park.

That a bunch of old people come running after me, while throwing bricks to my head (and eventually killing me) ... i even have nightmares about this o.o

 

[wooty]

Probably death by zombies, watching Dawn of the dead as a child is probably not the wisest of ideas

 

[Tuddle]

I have Fear Of Wide Open Spaces and The fear of bees.

My biggest irrational fear is that whenever I go swimming in a body of water (regardless of if it's a swimming pool or lake or the ocean, I will find one of the giant super-intelligent sharks from Deep Blue Sea waiting to eat me like Morgan Freeman.

Yip Yip martians.

Yip Yip? What kind of martian is that?

They're...uhm, Muppets. Featured on Sesame Street during the 80s and 90s.

Sometimes I have this dream that I've been skipping one of my classes all year and I only find out a week before finals... I wake up drenched in a cold sweat every time.

 

[Quaxar]

Yip Yip martians.

Yip Yip? What kind of martian is that?

I suppose it's the kind from Mars Attacks.

Spoiler: Them

EDIT: ninja'd, and I was wrong. Shame on me!

OT: I live in constant fear that R'lyeh rises again. Better find a cult to join.

Heights. Whenever I'm high up I fell like I might fall.
