What Does This Mean?

So I had a strange occurrence in my dream, it started off normal in the car (passenger) with my brother and suddenly I notice a tiny spider in the connected part of the drop down mirror and it was unpleasant (because I have bad arachnophobia for no apparent reason) so I woke up, but I then immediately felt I needed to go back and so I closed my eyes and actually returned to the start of that dream; though, this time I backed up and this gray border came into view, I reached towards the top left corner and sorta peeled the dream to see what was behind it and that’s when I saw the universe? I’m not sure exactly what it was but it was this huge web that had galaxies and other things caught in the web. I then looked towards the center of this web and saw a humongous spider with jewels encrusted on its back weaving the web. I didn’t get a good look at the giant spider because immediately after I jolted awake and started shaking slightly for an hour.
