Shit is like "Fright Night", get you a nightlight

from Joe Budden (Ft. Pusha T & Styles P) – Dessert 4 Thought Lyrics on Rap Genius

Meaning

Fright Night was a horror movie released in 1985 about a main character that loved horror movies but was frightened when his life became a horror movie because his nextdoor neighbor was a vampire. So this line say that “shxt just got real” and now this person is scared because he doesn’t know what to do.
Or he could just be saying that the situation is scary like a scary movie night is to a child who still uses night lights
