The 'recording our history', to me, is literal ... she's really painting on the walls of the apartment that they shared. I think she really did it. Ani was an art student at the New School, and the other songs from this period (Out of Habit) employ painting as a metaphor. The wall will get painted over when they leave, and their history will be painted over too, details forgotten, no longer shared, when they break up.

"The deep" is just sleep, because it rhymes.
