Spiders are well-known to hold grudges. They'll sit and wait until you're sleeping, then repel from the ceiling down to your pillow, crawling silently and stealthily up to your mouth or ears or nose. Then they'll choose which opening is best suited for them to lay their eggs. After that they climb back to their hiding place and await the hatching of their brood.
Haven't you ever heard the story of the lady that woke up one morning to find what she thought was some kind of pimple? After a couple of days of it growing and becoming more & more uncomfortable she started itching it. The skin suddenly split and hundreds of baby spiders poured out.

Sleep tight, girlies.
