Sightmare 

Something that looks so wrong or awful it can cause nightmares or cause you to think you're having a nightmare.

1) Oh. Em. Gee. That is like suuuuch a sightmare of a dress.
2) Hey, that guy over there...? What a sightmare.
3) The puke in that room is such a sightmare. I felt sick when I saw it.

Sightmare 

Something so terrible, one would only expect to see it in the most terrible of nightmares, yet there it is, in real life, right before your eyes.

Dude, I had a nightmare that I saw x-men origins: wolverine, and it was just terrible.
No dude, I was with you, we saw it yesterday, and safe to say, it was a sightmare to say the least.

Lord of nightmares

Progenitor of chaos and vengeance. The anonymous enemy, the unknown artist of freedom. the son of sin. whatever you wish to call him, junior the forbidden one. “Junifer Morningsnout” is a true force of nature who derives from the unknown which is partly what makes him incredibly terrifying.

he can look very innocent and Beautiful but he’s NOT what you think he is. Fair warning to anyone who crosses paths with him, can be trans on rare occasions.

Known also as “the master of ambiguity”

J has an appetite for destruction that nothing can satisfy, as said by anyone who’s ever met him/her

The lord of nightmares seeks to subjugate the world and have it at his mercy, for no one is above his wrath

Within junior lies no forgiveness and if angered or wronged then he/she will know why they call him the “lord of nightmares”

“I am the son, the darkness and the fire, for no one comes to the beak except through Me” -junior, lord of nightmares

Lord of nightmares is junior’s title

A polyester nightmare is overwhelming, shape and color combinations often seen in disco and Hawaiian clothing especially of the seventies.
