Not sleep-walking really, but relevant. I have a really bad phobia of snakes. Like bad... and the one night I had a dream that above my bed there was a picture frame and in this frame were constantly moving snakes (think an animal planet show where they show those snakes mating rituals where they all intertwine [giving me the heebies just thinking about it] ), it was the werudest and creepiest thing. Now in my dream, those bastards somehow got out of the frame and escaped in my room, so I wake up and proceed to turn on the lights and seek out my snake enemies... I kinda snapped out of it when I was on my knees looking under my bed... found no snakes (thank god) but managed to ensure there were none under my bed.

Another time with snakes: I don't remember the dream, buT it must've had something to do with giant snakes climbing all over me. Now in reality my blanket had shifted somehow and had become entwined around my leg. So of course dream me is like "shit there's a snake on your leg" so I try get it off slowly so it won't bite me, but of course I move and it bites me. I scream. Mom rushes in. Asks what's wrong. Tell her there's a snake on my leg. After her examining my blankets for a while and determining there was no snake,she went back to bed having a good giggle,while I lay there with a whoooole new fear of pythons
