I believe this part could be about Lana’s mom. Her mom being a gatekeeper, telling her she’s not going to be successful as a singer when that was what she wanted to be. The gatekeeper carelessly dropping the keys on my nights off” meaning even when she’s not working and trying to , that gatekeeping person is still is dropping those keys, that she’s not going to succeed. The “monsters still under my bed” line could be about that, Lana being afraid of her mom when she was younger, that fear still fucking her up now. It could also be about a relationship, a guy being a gatekeeper, maybe a record executive back when she was younger downatthemeninmusicbusinessconference possibly. She has a weak mission statement (personal constitution) because of those monsters, whether that’s actually alcohol or her mom and the gatekeeper.
Very interesting song. The more I listen and think about it, the more I wanna dissect it. If we go with the idea that this line is about Lana’s mom, maybe the change in “writing on my walls” to “writing on your walls” isn’t a change from herself to the listener, but instead, a message to her mom or whoever the gatekeeper is.
