noctophobia 

The intense change of emotions that occurs when the sun sets. Often non-frightening things turn very scary when night approaches and you are laying in the bed. Symptoms include: imagining the broom in the corner is a serial killer coming to murder you, carrying around a baseball bat just to go to the toilet, and burying yourself beneath mountains of blankets so the horrors of the night do not get you.

Oh my word! When my phone vibrated on my dresser last night, I was so freaked that I bashed it in with my fist.

Wowzers, dude. You must have had a serious case of noctophobia.

Necrophobia 

Necrophobia is the irrational fear of corpses, not just those of people but animals as well. Also included in this fear are the people, objects and ceremonies associated with death such as undertakers, morticians, coffins, tombstones, cemeteries and funerals. In a another way necrophobia could also be used to mean a fear of the dead by a cultural group, that their spirits will return to haunt the living, causing them harm in some way.

In some cultures necrophobia would be totally alien as the dead are welcome among the living.

noviophobia 

Noviophobia is an irrational fear, aversion to, or jealously of others' relationships at large, especially of potential romantic partners already being in relationships. Noviophobia is derived from the Spanish word "Novio" (meaning boyfriend) and Greek word "Phobos" (meaning fear); This strange word was featured in an issue of Nintendo Power in a fan letter regarding the 2004 Nintendo DS game "Sprung", and it was also mentioned in the 2004 Sonichu newsletter "Sonichu's News Dash!".

To make a long story short, I developed a fear that all the pretty girls are already paired up with a boyfriend. I’ve dubbed this social phobia, Noviophobia, after the Spanish word for boyfriend.
