In a lot of introductory philosophy courses these themes get brought up (see also: The Matrix, Total Recall, and many, many other movies!). If you had the option of choosing to live in the real-world full of some pain and suffering or a living in a dream-world full of happiness, which would you choose? In the real-world you may not be happy all the time, but you at least know what's true or what's real. In the dream-world you won't know what's true or real, but you will at least be guaranteed some kind of happiness. This is a difficult decision for a lot of people, but for Chris Brown the answer seems pretty clear.
While I have no idea how the lyrics of this song make any sense (see for yourself!), let's try to get a big picture of what's going on. If this love is a lie (i.e., if the love that Chris Brown is feeling does not actually exist in the real-world), then Chris Brown must be dreaming (or in a dream-world). If the love can only be found in the dream-world, then he'd rather stay in the dream-world even though it's not the real-world.
While this option does not seem to be unpopular, the weird thing is that the option to choose the dream-world over the real-world is made without any supporting justification! Why stay in the dream-world? Well, I'm assuming it's because that's where this love exists. However, we are not told why this love is so great, or why we should believe that it cannot be had in the real-world. Now, to be charitable, let's grant that it is a special kind of love (which it would have to be if someone loved Chris Brown at all...) which can only be had in the dream-world. Even if this is the case, why would you abandon all the other truths and joys that come with seeking an understanding of the real-world for a dream-world that contains this kind of love? Seems pretty selfish to me... then again, I would expect nothing less from Chris Brown. It's bad enough to abandon the real-world and the ability to contribute to other peoples, as well as your own, understanding of the real-world, but to do so for what would clearly be a false or pretend love! That's just tragic. Remember, given that this love exists only in the dream-world, that means this love would not exist in the real-world; thus, it's not really love! It's just a fake version of love. In other words, it's a false love, or, a lie. So, Chris Brown would be abandoning the truth and understanding, and a shot at real love, for a fake love. Doesn't make much sense to me...
I don't know about you, but I'll take the real-world any day. Even with it's uncertainty and painful experiences, it still seems better than a lie... but that may because I get joy from seeking an understanding of the real-world. Not Chris Brown though. Of course, the dream-world is probably the only place that Chris Brown can find love these days. Anyways, it's a tragedy that a quest for truth and understanding could be ended so early. An inquiring mind lost at the young age of 23... such a waste. Chris Brown's quest for truth and understanding: dead at 23 (1989-2012).
