What is This, I Don't Even...

Have you ever had some weird, disturbing dream that doesn't seem relevant to your life whatsoever? I need like a dream interpreter or something because this one creeped me out to no end.

So there was this giant yellow spider sitting on a table. This big ugly caterpillar crawled up to it around back and started nibbling at the spider's abdomen. It chewed this huge hole out of which spider guts were pouring from. The spider didn't seem to notice yet. The caterpillar proceeded to climb inside the spider, empty out the spider guts, and barf up a large quantity of caterpillar eggs. Then it started squeezing through the hole, all slimy and yellow and covered with spider juices, and crawled over a few inches away from the spider. The hole sealed up as soon as the caterpillar was free.

Then the spider decided to notice that there was a large scar on its back and its insides were completely devoid of necessary body systems and replaced by caterpillar eggs and started screaming. It was a horrible, high pitched keening. It was probably the worst part of the nightmare aside from what happened next.

The caterpillar eggs had incubated inside the spider for some time and had begun to hatch. Little miniature caterpillar babies began to gnaw their way through the spider's flesh and crawl out to their mother. The spider flailed around wildly and began to scream louder. The caterpillar babies were crying and everything was covered in spider blood and guts. The spider's legs were splayed in every direction and twitching madly. It looked kind of like this:

At this point, I appeared in the dream. I grabbed a large knife off the counter and began hacking blindly at anything that moved. Baby caterpillar guts mixed with those of the decapitated spider, who was still screaming, and unidentifiable pieces of bug flew through the air, splattering on the windows and walls.

It was basically a bug massacre.

What does this mean?
