Nice idea. I like this.
Hmm..BMTL...
Well we all know the origin of the first two lines...the Amy-in-the-restaurant story, where she realized how unhappy she was when asked if she was happy.
But I see it as meeting someone who opens you up in a different way, who seems to understand you when no one else does. Hence, "how can you see into my eyes like open doors". You spend more time with this person and s/he gets you to open up to them and you really start to like each other. You view the past as a time when you were numb and everything was monotonous. You feel alive with the person, alive and vibrant, and the person comes to realize that s/he feels the same about you. S/he has woken you up, as it were, and you don't want to go back to sleep.
And...yeah. The end.
