Things that creep me out, starting with the obvious:

Spiders, especially when David isn't home.

Horror movies, especially at night.

Going into dark rooms, especially at night (duh!) and after watching a horror movie.

Hair, especially in the shower and even if it's mine. ICK.

The aforementioned hardened lotion that always collects around the spout of the bottle or tube.

I love cats, but seeing a lot of them at once... like 10 would make me queasy. I don't know why.

Broccoli sometimes, especially if lots of the sprout comes off and you're left with that scraggly looking, jaggedy stalk. This happens sometimes when I use frozen broccoli. Now I just chop it all up before adding it to something.

Squash. Mushy. Icky.

Anthills.

David eat peanut butter and mayonaisse sandwiches. Well, ate really. He doesn't do that anymore. YUCK. I'm gagging just thinking about it.
