Dreams.

To post number 663: I just randomly found out online that LEGO Avatar actually exists. It's true that it hasn't been produced for a long time, and the series is very limited, so a small air temple costs $300, and a single Aang figurine costs $70 (that's quite a price). But what's interesting is not that, but the fact that in a dream, I somehow guessed that something like this actually exists.
