I think this is the sort of thing that philosophy is good for. If you want to talk about questions like, "what is truth?" or, "what counts as real?", philosophers are the people you want to ask.
Unfortunately, I don't think there is a succinct consensus quite yet.
Speaking of, I recently started listening to the Philosophize This podcast, which attempts to give basic overviews of some major philosophers and schools of thought in a generally chronological order. I'm really enjoying it so far, and while it's probably easier to download and organize them with itunes or an app, the episodes are here:
I found it at times a bit too pop-ey, and once I realized the voice was a bit too much like Peter from Family Guy I stopped listening entirely. That said, I'd recommend it. Many of my friends loved it.
Another somewhat more in-depth but possibly slightly more boring podcast is "A History of Philosophy Without Any Gaps". There's at least one spin-off on African Philosophy. I really enjoyed the almost-boring slow-paced nature of its approach.
