A String-like Cloud In The Sky Of May, What Does It Remind You Of?

The two photos on the top row are showing a typical style of Japanese dragons. The Image was originally imported from China in ancient times. The shape is the same as typical Asian dragons, but it is clearly different from the images of dragons in Western countries. 

Comparing to dragons in Western countries, Asian dragons looks more like a big snake with the four limbs and don't have wings although they can fly. 

In Japan, dragons have been considered as one of the nature gods, but they are not always nice to people even though they have an aspect of being a good omen. 

Ancient people related them to water, and thought they can control/bring water disasters such as storms and floods. Thus most shrines which worship dragons are usually located near water in Japan and typical images of Japanese dragons show dragons flying in a rain clouds or in a thunder storm.

So it is easy to be reminded of a dragon when people see a string-like cloud in the sky especially with a rain clouds in dark gray color. Well, do you see any dragons in the photos on the middle and bottom row?
