Reading wrong

I have put the articles about my bad listening comprehension series. Considering my English level, this series must continue.

I often do, not only "hearing wrong", but also "reading wrong".

When I read,
"Bill fell down some steps."
I thought he felt down. So...
He was depressed about... steps? I see. I guessed he tried to achieve to do something step by step, and he probably felt depressed on the way to his goal.

"This soup is very salty."
I thought it was soap. So...
Soap is salty? I see. The soap includes famous salt which is good for skin, such as the salt of the Dead Sea.

How imaginative...
