Yeah, I hear the hum all the time. It's my neighbor's fucking washing machine. Just kidding, no, but seriously. I don't know if it's like the blood moving in my brain, or I've honestly recently googled like auditory hallucinations and autism, because when I lay down in bed at night, I swear to God, I start to hear, I'm like, who the fuck is playing music? Where is that bass coming from? and then I sit up and I don't hear it anymore.
