Was it the hairy spiders or the monster under your bed that made your skin crawl as a kid?

We may laugh at the things we were once scared of, but it's not surprising that many adults are still scared of creepy crawlies, dark spaces and creaks and cracks in their homes.

Being scared and fearful is not only common, it's completely natural, says Natasha Sharma, a psychotherapist based in Toronto.

"There's two types of fears. One is natural, as humans we are born with the ability to feel fear and we need this in order to determine everyday threats — basically animal instinct," she says. Sharma says the second type of fear occurs when we're exposed to other people or overwhelming experiences in our lives that inflate our sense of fear.

"This type of fear is irrational fear and it varies by person. Some people will always be more fearful than others," she tells the Huffington Post Canada.

A certain amount of fear has always been ingrained in our everyday lives. As children, we're told not to let the bed bugs bite, and as adults, we grow up with horror legends like Jason, Freddy Krueger and Bloody Mary. So any time you see a flight of stairs and expect a creepy little possessed girl to crawl down (backwards even), Sharma says that's when our fears remind us of movies and shows that have reinforced this feeling of unpredictable threats.

And there are some people, of course, who just love the pleasure of being scared. When our brains know there is no risk of being harmed, the rush of being scared becomes satisfying, Sharma adds. Psychologist David Rudd told LiveScience.com that this heart-pumping and fast-breathing rush could also explain why people like skydiving or bungee jumping.

The fears of flying, swimming or sleeping in darkness — which are more common than any others — can slowly be tackled by simply "facing your fear," Sharma adds.

"A person who is afraid of flying can slowly overcome their fear by flying. It may not eliminate the anxiety, but it has a higher success rate of reducing it," she says, adding that often, the fear of flying comes not from any real danger associated with flying, but instead, a fear of death.

She also recommends calming your body by taking deep breaths to bring down the heart rate, a particularly important tactice for those who are constantly experiencing fears, as with taking the elevator or walking through a dark alley, for example.

  • Zoophobia

    Does this kitty scare you? Zoophobia is the fear of animals. Even though there are specific fears of reptiles, cats or dogs, you will never find a zoophobic with a pet -- and if you have a kitty, forget about being friends.

  • Caligynephobia

    No, this isn't the fear of Salma Hayek, it's the fear of beautiful women in general. Caligynephobia often has phobics feeling anxious, stressed and experiencing panic attacks. Like most phobias, it's assumed to be caused by a correlation between beautiful women and a negative event -- so gorgeous gals, make sure to let potential suitors down easy.

  • Agyrophobia

    If you're an agyrophobic, the idea of jaywalking is probably your worst case scenario. Agyrophobia is the fear of crossing streets, highways and other roads.

  • Gymnophobia

    This is just half of the fear. Gymnophobia is the fear of nudity that can leave people often worried about being naked and seeing others naked.

  • Arachibutyrophobia

    One PB and J sandwich, hold the peanut butter. Arachibutyrophobia is the fear of peanut butter sticking to the roof of one's mouth -- usually leading to panic.

  • Ephebiphobia

    If the thought of Justin Bieber makes you want to hide under your covers -- you're not alone. Ephebiphobia, a social phobia, is the fear and prejudice against teenagers or underage adolescents.

  • Autodysomophobia

    Autodysomophobia isn't just a phobia for bad smells -- it's the fear of people who smell bad in general. From poor hygiene, disgusting odours and rotting foods, this fear often leaves people avoiding cramped spaces like subways and buses.

  • Ancraophobia

    Hold on to your hats, ancraophobia is the fear of wind. People who have this fear tend to panic during weather changes like storms or hurricanes and is a sister to aerophobia, the fear of air.

  • Pteronophobia

    Everybody gets annoyed by being tickled by feathers, but pteronophobics really hate it. The fear of being tickled by feathers -- and feathers in general -- results in rapid breathing, irregular heartbeats, excessive sweating and nausea.

  • Chorophobia

    So the next time you don't want to hit the dance floor, you could just say you have chorophobia. The fear of dancing (Beyonce should be a mentor to overcome this fear) leaves people anxious and in some cases, even fearful of losing their lives if they dance.
