Childhood fear

I have no idea why but i'm really very afraid of tiny circular substances when i was young. It makes me feel very icky and i just can/t help keeping my eyes away from it. Sometimes when i have allergies on my hand, i just feel like scrapping off my skin instead of torturing myself looking at it. Although i'm afraid of all theses circular things, i forced myself to look at overgrown cancerous cells. Those that are in a ball form. I believe there is nothing that i can't overcome and I the cells actually doesn't irritate me that much. I even enlarged the pictures to take a closer look at it. That's how crazy i am.
Besides that, I was always afraid of the dark when i was young. I shifted to my new home when i was 7 and i actually have my own room. I was always very afraid to sleep alone and needed my dads accompany. Until when i was 8 or 9, my dad eventually stopped accompanying me. I could sleep but every night before I fall into deep sleeps, I would have to wrap myself in the blanket like a wantan. Of course i've grown up now and i'm not too afraid of the dark anymore.
I remember when i was 8, I watched a Thailand horror movie ALONE. At first, i remember watching it with my dad but after that when i looked around,there was no one but me. I had no idea why but i stood still in front of the television. Well of course i freaked out after that and I don't watch horror movies till now and I don't think i would every watch any anymore.
I don't really like going to the cinema too, I even cried when i was watching cars...and of course other shows like narnia and harry potter but of course I don't cry now.
