It’s a reference to an old Reddit post where somebody had the same situation I did where they met someone yand fell in love and had long and happy life until they started noticing a lamp in their living room that sidn’t look right. Drove them crazy in this dream and eventually forced them to wake up. I’m on mobile and can’t find original post ATM but that’s the jist.
