I had a scary lightmare during my 3pm nap

For the training seminar, I'll provide the hardware and software, but I'll need the hotel to provide the lightware.

Christmas Lightmare

The inevitable tangled mess of Christmas lights.

C'mon-you know what it means... You have had a Christmas Lightmare no matter what your skill.

Lightmare 

any intersection that is a pain in the ass to make it through because the lights are so poorly timed or too quick to change therefore allowing only a few cars to make it through per cycle.

A five street intersection in rush hour is a huge lightmare! light-mare lite-mare

Lightmare 

The antonym for “Nightmare”.
Instead of an unpleasant dream that induces negative emotions, it refers to a pleasant, comedic and laugh-inducing dream that causes situations of strong pleasure and comfort; potentially causing the person to wake up later than scheduled.

A: AHAHAHAHAHAHAHAHAHAHAHAH-
B: Why did you laugh? Did you lose it due to 1 of your nightmares?
A: It was not a nightmare, it was a lightmare. The scenes were too funny… XD
