Reoccurring dream:<br/><br/>I'm walking down a street/alley/road next to a very tall wall (so tall that no matter how hard I try to look over it I can't.  Especially in subsequent dreams).  The wall turns into a box/dead end.  Then all of a sudden these mechanical spiders as large as a medium sized dog come crawling out of just everywhere.  Walls, ground, everywhere.  It's more like they just appear too.  I know that if they sting me I'm dead, so I start to flee.  Except there's no where to go.  It doesn't matter if I climb onto a dumpster or try and climb a fire escape, they always get me.  Of course, right before they sting me with something that looks more like a syringe than an actual insect stinger, I wake up.
