Is it normal that i'm repulsed by lotus seed pods?

I remember as a child I would see a lotus seed pod and freak out, and it still goes on to this day. When I see them it just makes me feel like all of the energy is draining out of me and my heart starts to beat really fast. I don't know what it is about them, but I just can't look at them. I also remember being on 4chan one time and seeing a picture posted of a hand with similar holes in it and getting the same feeling. In fact, I'm getting quite upset just thinking about it in order to write this.
