No way!
What does it do? Look around and crawl back out? Go through your intestines like it's a water slide?
My preferred protection is my CPAP mask.
As far as raining goes: watching the video was SO creepy!!
Watching the spiders walking around upside down in the air connected to some invisible web was really weird.

It's one of those times when I'm fascinated and want to watch and figure it out, but I'm also extremely repulsed and want it to go away. KWIM?
So, how ARE they all up there? Did they make some kind of giant web from the power lines?
