Three things I was afraid when I was a child.

El chupacabras: I remember the first time I heard this name, I was a child and I still lived in a little village on the Andes, the mountains of South America. In those days I believed all the news that I saw in TV. Indeed, the “chupacabras” were treated as a serious news in the 90’s.

UFOs: In my country the blackouts were usual and in one of those blackouts my family and some friends decided to wait for the return of the lights in our patio, illuminated by the full moon. Suddenly, a big light as big as the sun crossed the mountain very slowly and disappeared close to my grandparents’ house. I thought that an extra-terrestrial had decided to get out of his ship and live hidden there (like E.T).

Bats: Once we had in my village a plague of bats. A friend of mine told me that those bats are vampires and they feed on blood, so when we saw a bat we covered our necks and some friends made a cross with their fingers to frighten them way. We hadn’t ever seen a bat before, as those animals weren’t common in my zone.

[Very good.  Most of the corrections were minor or had to do with complex use of tenses. Note that 'news' is considered uncountable and is therefore refered to in the singular.  You can talk about items of news in the plural.]
