Doesnt this prove the theory that bugs go inside our mouths while were sleeping?

This only proves that a Spider is living in your cereal bowl cupboard.  Perhaps if you bothered to remove Spider webs, they'd go elsewhere.  Spiders do sometimes crawl into ears, but I doubt they'd enjoy climbing into a warm wet place, such as your mouth.

Spider Flakes sounds like it would be an important part of a nutritious breakfast.

Weird, that's been three days in a row.

Here in Australia the Scientists believe that while we sleep at night, we consume the average of several spiders in our lifetime. No joke.

What kind of spider was it that you found in your brekkie cereal?
