If your nightmares can come true, your dreams can too, which is literally the only positive thing you'll learn from a 2015 study on flying spiders.
If you don't believe me, there's a video to prove it.
If you already thought spiders could fly, you're not crazy. Most spiders appear they can glide or fly because of their spider silk. This strong protein fiber is barely visible when it's a single strand, which helps arachnids float through air or glide away from danger.

There's approximately 10 million known species in the tropical rainforest, which means survival of the fittest is crucial. Species that are unable to adapt in competitive environments are left to die.
According to the study published in the Journal of the Royal Society Interface, some tropical spiders can fly without the use of their trusty spider silk. This is great for them, but a scary realization for people...
