Well the suface meaning is basically that he's slept with this chick and he doesn't want her to just walk away without saying goodbye in the morning, he wants to make it a relationship.
But.....
If you look deeper you can maybe infer that he's having a dream about a girl he loves, and he doesn't want to wake up, ("I feel the sun creeping up like tick-tock/I'm trying to keep you in my head...")
and when he's experiencing reality, which he perceives as a lie, he wants to go back to sleep to revist his love. So maybe he's denying the truth here. ("Let's run away from these lies/back to yesterday safe tonight")
