Drowning in spiders and snakes.

I keep having these dreams where I fall into water.
A lake, and ocean, a swimming pool... whatever. When I fall in, I'm above the water, but then I sink. I keep on sinking and sinking, and once I get to the bottom I use all my strength to propel myself to the surface, but I always fail.
When I gasp for air, I get it, but I'm still submerged and it gives me the feeling that I'm am already dead.

I also have a lot of dreams involving overwhelming amounts of spiders, scorpians, or poisonous snakes. In the dreams I can actually feel the venom take effect. It's very strange.

Farewell fellow dreamers, and may your forheads grow like the mighty oak.
