I just discovered this sort of thing in my bathroom, it's the first time seeing one, they aren't even supposed to live where I live and I have now officially a phobia.
Through the years I have believed that I have loads of phobias, but now I know the difference between being afraid and having a phobia.
And harmless or not, I'm not capable of stepping down of my bed and on the floor even knowing that that thing is dead and somewhere in the sea.
But still, thanks for posting this, it puts me on ease knowing that those things are not dangerous to humans, although I had to cover the computer with a book when I saw the centipede, since I couldn't watch it and clearly not put my hand anywhere near it.
