Have you tried moisturizers? My whole body gets itchy when I break a sweat, and I'm pretty sure that it's just dry skin for me because moisturizing tends to work pretty well.
As a child, I hated brown bread, now, I like it, especially seeded, more than white bread. I transitioned when I really wanted toast and jam and there was only brown bread.
I bite my fingernails to the point where they bleed and scab up- more recently I started doing it in my sleep.
I think I made the same transition for exactly the same reason I can't eat white bread now. It gives me indigestion. Brown bread all the way. I love seeded bread too, but the though of white seeded bread makes me feel queasy. Mushy, pasty, gluey bread with chewy bits of seed inside it. I do this too. I've got scars on my fingers and thumbs from doing it. I don't know if I do it in my sleep though.
W.D. Wallace, you cracked me up! I too am always tempted, and fail miserably, peeking behind shower curtains in someone's home. Even though, once at a guy's house I had dated a few times; that peek was so scary, I never went back!
I pop and snap my joints. A lot. I usually don't even realize I'm doing it, but once I've started, I can't stop until they're all popped. It starts with my fingers, then continues to the upper fingers, then the thumbs, then the wrists, then the shoulders. Sometimes the back and neck if I happen to be standing. I don't even really know why I do it, I just can't help myself. I've really freaked some people out with it, especially with how fast I do it. I usually go through all of those joints within just around 10 seconds or so. I know it's sort of a weird and off-putting habit, and I guarantee it's bad for my body, but it's just something I've always done and I can't shake it!
I have to make a new cup of tea every time I finish a project at work to celebrate the start of my next project.
Apparently, I dislike wearing rings in my sleep. Whenever I neglect to remove them before bed, I wake up the next morning bare-handed, which leads to a frantic search in the bedding. They're not loose, so at some point in the night I'm physically taking them off. Wish I had video of that because on more than one occasion, I've found them safely tucked inside my pillowcase. ETA: Conversely, I have to put them on before I can write, even if I'm still wearing pajamas because my hands feel odd on the keys without them.
I often play with my hair when I’m reading or writing. It’s become a habit to run my fingers through it or twirl a lock around my index finger. I also crack my joints a lot. Another weird quirk of mine is that I’ll laugh hysterically in moments of high tension or emotion. Like family reunions or family arguments.
Not sure if this counts for a character-quirk but I have an extreme aversion to the sound of pencil lead scraping across paper; it's such a horrendous shock to my system that I am unable to be around it. This is by no means the weirdest thing about me, but it's one of the things that terrorized me ever since I was little.
