Explanation of Facebook referral paths in Google Analytics

[theLotter]

In the past month I have seen a huge increase in the visits + conversions from Facebook (which is obviously great).  However, from Google Analytics it appears that most of my visits are not coming from my brand page.

Is there an explanation of what these referral paths mean?

Top Facebook referral paths:

/

/l.php

/home.php

/ajax/emu/end.php

/brand - much less visits than above URLs
