I had a dream last night where I woke up in the middle of the night and then walked up to my loft. There was a huge spider web being spun by a giant spider. It then chased me into a corner. I ran out of the house onto the street and continued to chase me through my neighbourhood. I woke up before it caught me.

It is interesting that you have a dream about being chased by a spider, i've had a few dreams before myself of being chased by several spiders.

Spiders have many meanings, I am not too sure of a lot of the meanings but I know a few of them. Spiders are reflectant of the 8 paths in life. or rather 8 lifes to the center (nirvana). Some people say that this is 7, but generally speaking it tends to be 8.

Spiders can also reflect all are fears in life, regardless if you are/are not afraid of spiders. So basicually you could say you are running away from your fears or it is that your fears are catching up with you, possibly and most likely things that have happened in the past which you think you are but are not really letting go of.
