Hi Jenna,
First all, I just want to commend you on the Bible Basics Site. You are certainly doing your bit to reflect Christ. Your viewpoint and writing are truly refreshing.
About your dreams. Can you tell me what your associations with the main symbols are and/or how each of the dreams made you feel. It sounds like the first dream was disturbing and frightening. Do spiders in general disturb you or were they just disturbing in the dream?
The beetle dream sounds amusing. It sounds like you may have a more positive relationship with beetles?
Just right off hand, the beetle dream almost sounds like some kind of message trying to get through, perhaps something you aren't noticing that's trying to get your attention. The "new guy" is probably some kind of animus figure (a positive one at that) and he's trying to get your attention.
And although it does sound like the first dream was disturbing, I'm wondering if it might actually indicate the emergence of some creativity, or some new phase of life - something that is good, but that, simply by virtue of the fact that it is new is startling and frightening.
Since the spider's nest was on the windshield of the car and since cars are often symbols of ourselves, it again sounds like there is perhaps something going on that you can't see and maybe that something is something creative, fun, and as original as an ornate beetle!
What was the sequence of these dreams? Was the spider one first, followed by the beetle?
In the mean time, here's a link to an article I wrote about spiders:
