The funny thing about spiders in dreams is they have a broad range of interpretations from fear to goodness.

Let me just say that I believe that dream symbols are very personal and what means fear to one person maybe joy to another person...

I have a dream book that translate most symbols into something dark or negative because the book was written in the 'olden' days. I got a kick out of it's spider meaning.
Basically according to it, Spiders are a bad thing to dream except... gold spiders and apparently gold spiders crawling on you or interacting with you are signs of positive things to come. lol
Isn't that odd? I wonder why gold spiders would be a positive.
I think it's rather humorous to ponder on as to why they thought that way back then.
