A disaster happened while I was starting an Italki discussion

A few days ago I started a discussion named "What's your favorite Latin-American country?" since I was curious about it. However this (that) is not the point of this entry. I want to tell you what was happening while I was doing that.

It happened last Sunday about twenty-two o'clock. My parents went to bed early since my mother had to wake up at 2am to travel. My sister went to bed early as well because she had school (the) next day. And the only person awake in the house was me! I closed my bedroom's door and I turned my music on. Two hours later, I ended up my discussion and I decided going to the bathroom..brushing my teeth and finally going to bed(<-- to go to the bathroom to brush my teeth and finally go to bed). Once I was done I went to bed. I was very con(m)fortable. (I was) Just about to sleep...and (when) the telephone rang! I ran to answer (it) and I got the bad news.

How to explain this convoluted happening(stance)...well, resuming the series of unfortunate incidents (events) that caused this disfortune; the parking basement of the residential compound where I live, flooded for unknown reasons. Therefore, the water turned our cars into useless pieces of tin late (tin late??). The water level was 1,50m, so we couldn't see the cars. But that's not all. If it were (wasn't) not enough, the lights went out (too).

The funniest part of the story is when my neighbors noticed the basement (had) started to flood, they came to our home to inform us, but the only person awake was too busy listening to music and discussing trivial matters.
