I can feel it but I’ve never seen it. Is a knockable head area enough evidence I still have mine?
Imagine there's a 4D creature living in your walls and when you sleep it comes out and takes your skull out of your head through the 4th dimension, but it always puts it back before you wake up. Then one day you wake up earlier and you go all octopus mode.
You boney creatures are weird. You have hard things? And you keep them inside your soft parts? How do you squeeze through any size aperture?
