2.
An intensely scary event occurring in your imagination while you are awkwake.

Like a day dream, but a horribly frightening one, such that it is more like a nightmare.
Aw man, what if that hott girl I hooked up with was my cousin? Shoot, I gotta go rip my eyeballs out!
Relax, man, it's just a daymare. She's not your cousin.
You're right... Grandma just said she's my sister's cousin.

it is having a nightmare during the day while one is awake. usually leads to the person to sleep in order to escape the horror that was presented during the incident. there could be multiple incidents in one day of extreme horror. it simpler words it is like having a bad day, yet so much worst that it leads you to hope the next day will just come already.
William: Hey Dude come check this out, it is gruesome!

Tyler: yea sure.... OMG!! WTF IS THAT?!?!?!... NO! Nevermind.. I'm Out!

-Hours later-

Tyler: Man... that was disturbing and it wont get off my mind. what a Day-mare today was... I'm just gonna go to sleep and hope tomorrow is better.

A vivid, unpleasant mental image (as in a nightmare) conjured in broad daylight, such as an impending crash, or a thought of a loved one in distress, which can cause a strong emotional response such as fear or horror.
Scott still isn't home from the game, and I'm having such a daymare! I know he's stretched out on the pavement somewhere.

A good dream while sleeping. As opposed to nightmare.
A daymare is okay, nightmares scare me.

Ebil monsters lurk in nightmares, but daymares have only good critters.
