Is it normal to have a deep hatred towards chalk?

Since I can remember, I have had a deep hatred towards chalk. I don’t know what exactly makes me hate it but I can’t touch it or think about it at all. The thought of chalk on my hands makes me so sweaty, the dry, powdery feeling disgusts me. Even thinking about it, I feel the need to wash my hands. The thought of it being on my hands, in the air as dust, or any chalk powder in my eyes, mouth, or anywhere else makes me feel so grossed out. I don’t know if this is a fear because I can look at a piece of chalk just fine, I just hate chalk with a burning passion. Is this normal? Does everyone secretly hate something others find normal? Please tell me your thoughts
