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.

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.

A seriously bad dream, but experienced during daylight hours.
"I had a nightmare yesterday."

"Oh? At what precise time did this happen?"

"During my afternoon siesta."

"Dude, that wasn't a nightmare. That was a daymare!"
