At a house I used to live at, the bedroom light switch was all the way across the other side of the room from my bed. I will switch it off, run, and leap into bed as fast as I could and lay there still as a stone until I felt it was safe to move again.
Yeah, I guess you can call me a little paranoid.
I also won't let my feet hang over my bed because I feel like someone will grab them. Same thing while I'm sleeping; I don't get how people can sleep with their arms, legs, etc. hanging over the side of the bed. And I always sleep with my arms under the covers, otherwise I feel like I'm not safe if I'm not completely hidden under the covers except for my head.
Also, I always NEED tp have my bedroom curtains shut all the way. If they are open or a little open at night, it will creep me out and I will become scared.
And lastly I'm deadly afraid of drowning. The titanic movie scared me so much. Just being out on a boat in the ocean scares me. I think about all the deep water and I'm not a very good swimmer at all. But the water is so deep if you think about it; it's miles and miles and miles and MILES deep. That just scares me to think how deep it is.
And I swim across a lake every year for this annual thing; it's not so bad, but I'm so scared that some snapping turtle is going to grab my toe or something. Under the water, since it's a lake, is so much unknown stuff. Nasty, yucky water plants and old things resting on the very bottom of the dark lake. And there I am swimming right above it all. Any creature could be lurking beneath me as I'm swimming in the middle of the lake, and it just creeps me out.
And lastly, another thing that I do is when I eat a cup of yogurt or pudding, I HAVE to lick clean the lid and I have to scrape all of it out before I'm done. I've seen people eat some and leave a bit in the bottom, but not me. I will scrape as much out as possible. Same thing with a plate after I eat breakfast, lunch, or supper. It all has to be completely gone before I'm done, unless I don't want to eat it.
