Yeh I've had quake dreams too. Also sometimes when I've been on the computer too bloody long & I'm browsing the web, I'll start to nod off & I'll start to picture quake on the screen instead.
Hasn't happened in a while though, as I'm not playing Quake so much these days, plus I'm not browsing the web all night long, every night, these days either.
BTW RGN, an Armarlite AR-10 is like a Armarlite AR-15, except its in 7.62 NATO caliber (.308) instead of 5.56mm (.223). Actually the AR-10 came out 1st, but it never really took off (FN-FAL had the 7.62mm business all sewen up), so really the AR-15 (M16) is really the 5.56 version of the AR-10.
