I've asked that same question. But aren't dreams nothing more but an expression of our subconscious thoughts? The things that lay dormant within our minds - the issues that we repress, that let themselves out whenever we sleep? Therefore, if we can express "love" within our dreams, then surely, it is our desire to love. Moreover, love can bloom within our lives if we allow it to. We just have to stop repressing it within our minds for a "field of dreams", and allow ourselves to experience it in reality. Just let go. But, by letting go, we also have to be careful not to loose ourselves to our desires.
I am drunk in case you're wondering. Surprisingly I can't see any typos.
