Cover art for Duermete lyrics by As Tall as Lions

Since Dermete is the command form of going to sleep, I think it's kinda about reminding yourself to put things in perspective and convincing yourself of something, like how you know you should be sleeping and are trying to convince yourself that 'better days will come' and that even though you feel a little lost everything will be fine- and to stop overthinking and go to sleep.
