A person lies awake at night, unable to stop thinking about someone who is gone. The speaker is trying to move on, and the poem is honest about how hard that is. Deleting a phone number, photos and old texts is easy, almost mechanical. But the speaker knows the real problem lies elsewhere: a face, a voice and shared memories can't be wiped with a tap.
What stands out is the strange twist in the first lines. The speaker doesn't want to close their eyes, yet the reason isn't fear of the dark. It's that the ex appears "in the blackness of my dreams." Sleep, which should bring rest, becomes a place where the loss is felt again.
The final lines are a little odd and quite telling. The speaker wishes to "sleep a sleepless night" without seeing this person, which suggests they'd accept even restless exhaustion in exchange for peace. The mood is tired, raw and quietly pleading.
