I just looked up what Spiders mean in dreams - thanks to Angiedw mentioning what Freud would think of spider dreams...
I came across this tidbit though - how interesting!
SPIDERS : Spiders are a little like snakes in that they usually refer to something bad in your life. They will usually refer to some situation where you feel trapped or stuck. Perhaps you dislike your job and wish to move to something more interesting. Perhaps you feel stuck in a relationship. Just think of those emotions about being caught in a spiders web. Where do you feel that same sense in real life or been unable to move.
I NEED A NEW JOB STAT!
