I remember having a few WoW dreams, mostly just of me as the actual character. I usually wake up after doing something normal, then realising 'wait...I can't do that can?' or something along those lines.
Most other dreams seem to involve Giant Mecha.
I have however had one very lucid DF dream, of me being a Dwarf in one of my fortresses (The Legendary Weapon / Armorsmith to be exact).
Rather a long dream though, I spent several Dream Hours (which is probably about 35 seconds) making a masterwork sword, then giving it to a Champion in gleaming Steel armor (fullbody plate sort of thing).
Everything was even a sort of full size, with 1 tile = about 3 metres square.
Hence the forge was essentially a small building*
Then someone shouted 'The Orcs have breached the main entrance! Everyone to Arms!'
I then ran to my forge and picked up a suit of steel armor and a (masterwork) hammer, and then ran to meet up with the other 140-or-so dwarves in the Fort, with the Military dwarves led by the champion with the sword, all in neat formation (about 20 or so of these guys), and then everyone else just in sort of rag-tag bands, or standing alone. Everyone either had a weapon or was hunched down, looking as though they were about to start a bar brawl.
Most of the Dwarves assembled were in their civilian clothes, in various states of decay, although some had leather or chain armour, and a lucky few had maybe a plate cuirass or some sort of full-face helmet.
Then the Door at the other end of the hallway burst open, and half a dozen ten-foot-tall green-skinned tusked Orcs leaped in, each wearing either no armour at all or some sort of plate-variant (covered in spiked, I think one of them had a kitten stuck on a stick attached to his shoulderpad) and wielding menacing looking instruments of doom (spiky maces, morningstars, serrated blades, that sort).
The Orcs began walking forward until nearly 80 of them were in the hallway (it was quite a wide hallway), then started jogging towards us in a rough horde, some elbowing each other to get to the front.
The Dwarves checked to see if everyone was ready, then the Champion held his sword up high and yelled something indistinct, and all the military dwarves started barrelling forward at an almighty pace, with the draftees all sprinting along beside them in a rough line.
Then, just as the Champion was about to meet blades with the Orc in the lead, a hulking monstrosity with an evil looking axe... I woke up.
My reaction to this was something along the lines of
'GODDAMN IT, NO!'Needless to say, I was somewhat pissed upon missing out on an Epic battle for the fortress. Even if it was just a dream.
