Dream prophecy is mathematically insane

I don't mind people believing in their dreams, as long as they don't draw reasonable people with them believing in what I think is nonsense. I hate books about dreams, I don't like people making money with dreams and certainly I dislike people who don't get one particular thing.

Say that there are 300,000 words in any average language. Then we have 6.5 billion people on earth, which is written 6.500,000,000.

Then we do this: for each word in any language, there are 6.5 billion / 300 thousand dreamers. That means there are 21666.666 dreamers for EVERY SINGLE WORD in a language. Don't you think a catastrophe is actually a word and each night there are 22 thousand people dreaming about such thing. How could this predict future in any way, as this happens EVERY NIGHT.

However, notice that there are lots of sixes there so my math is by satan and cannot be trusted.
