I actually have a phobia of lotus plants. It was bad enough that I couldn't look at that picture without almost passing out. (It would have been nice if you'd put a warning in the title).

I can't really explain why it has such an affect on me, but it's pretty nice to know I'm not alone.

Have to admit I'm not exactly afraid... but kinda spooked out by those dried lotus seedpods

Same here. I don't have an issue with holes in general but those lotus seedpod things are kind of creepy.

There is something mildly disturbing about it and I can't figure out why. I try to sort of will it way and then I kept clicking and looking back it, but it still bothers me.

Maybe because scary things crawl out of dark holes? Because you can drop things into holes & not get them out? Because you can hurt your little finger putting it into holes where it doesn't belong? How about Flash Gordon's Trial by Treebeast?
