noctalgia 

Literally means "sky grief". Noctalgia is a new astronomers' term for the feeling of loss of dark nighttime skies around the world due to light pollution from various sources. Those sources are artificial lighting created by humans such as outdoor illumination of streets, buildings, and other places, many of which are not required all night. Also satellites reflecting sunlight onto the night side of Earth from solar panels and antenna arrays. Most city dwellers can no longer see any but the very brightest stars. The glory of the Milky Way in a dark sky is something most people will never have the opportunity to see. Truly, we must grieve for that which we have lost in the night sky.
I can no longer see stars and constellations I could easily see as I child, their loss gives me a feeling of noctalgia, I am greatly saddened.

Noctalisk 

Noctalisk (noun) | Plural: Noctalisks

Definition:
A terrifying, nocturnal creature said to lurk under beds, preying on anyone brave (or foolish) enough to let their foot dangle over the side. Known for its sharp wit and even sharper claws, the noctalisk embodies childhood fears of the dark and the unknown. Often used humorously to describe irrational fears or the imagined consequences of reckless bedtime behavior.

Pronunciation:
/ˈnɒk-tə-lɪsk/

Origin:
From the Latin root “noct-” (night) and ”-lisk” (reminiscent of mythical creatures like the basilisk). Created as a modern neologism to describe the ultimate childhood nightmare, often referenced in humorous or exaggerated contexts.

How to Use:
Call something a noctalisk when it embodies lurking, unseen fears. Or use it as shorthand for the monster under the bed.
1. ”Don’t let your foot dangle off the bed—everyone knows that’s how you summon the noctalisk.”
2. “When I heard a creak under my bed, I immediately pulled my legs in. Noctalisk prevention 101.”
3. “Sleeping with one foot out of the covers? Bold move, practically inviting a noctalisk for a midnight snack.”
