"Even though I really like your place
Somehow we don't have to know each other's name"
And also about someone adrift in his life, with no clear plans
"They found our city under the water"
Could be referring to a place, a bubble created by lovers together,
once it's found the bubble blows and you have to get on with some new love,
because you don't want to live without love.
"Decide my past
Define my life
Don't ask questions
Cause I don't know why"
yup it probably is about one night stands
