You can't wake up in a coma, babe. I think you're getting it mixed up with being catatonic. Even then, I don't think you'd be aware of your surroundings. But do I know what you're getting at. That would be hell to go through if it were to actually happen. Personally, I'd hate to be paralyzed from the neck down.

And spiders aren't as bad as wasps/bee's/scorpions, IMHO. Those stinging insects are horrible. I'd even rather deal with snakes over them.
