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.
