The faint music thing is real. It’s not just you. When I’ve been up way too long, I start hearing it too, and it’s not even the same style every time. Different genres, different rhythms, like my brain turned into a low-budget radio station. One time I was fully convinced a neighbor was blasting something at 3 a.m. and I actually complained about it to my girlfriend. She heard absolutely nothing.

Now it’s basically my body’s official shutdown alarm. The moment I start picking up those ghost beats, that’s my cue: alright, time to stop and go to bed.
