This story effectively used gore. It wasn't just gore for the gross-out value.
I thought this story was pretty cool. What kept my interest up was the cause of the phenomena. A strange and interesting idea. Unfortunately, the end didn’t entirely convince me. Having dreams or nightmare come through into reality seemed a tad…trite? Anyway I was hoping for something more but maybe I’m just sick of the whole Myan. That said, I still would have like to see more of the aftermath.
I played a lot of Shadowrun, who used the Mayan calendar premise of 2012 and the shift to a new world, so I've had more than average exposure to Mayan apocalyptic concepts. Outside of the apocalypse-porn film 2012 and the History Channel shows moved to prime time to coattail off that movie, where has the overexposure of the Mayans come from?
Anyway, the horror of Lovecraft was that the universe was a vast, uncaring place where your greatest hopes and dreams were less than dust in the grand scheme of eternity. This story validated them, made them look valuable.
Dreams are powerful locations in the Lovecraft mythos. In the hands of the proper practicioner, dreams can be used to travel between dimensions or through space. Are you meaning "humanity" instead of "dreams"? I think the clarity is important, as the protagonist is someone who would have been one of those dream travellers in Lovecraft's world.
The worms were essentially Satan - the evil entity that provokes evil in mankind, that cares about the actions of every soul. That's stupid - but almost funny.
See, I took this entirely differently. I found the blood realm to be easily a place out of space and time full of things that want to eat us. The protagonist applied his perspective of why everything was happening. I jumped again to Shadowrun, where the blood magic finally allowed the gap to close between our world and that of the horrors. Now they can come through and run rampant. I felt the ending was nice and open. Maybe there will be the establishment of a new religion to worship and serve and feed the new masters outside time and space. Maybe others will rise up to oppose them.
Any story that inspires other stories in my head is a winner in my book.
