OP, you have now discovered the secret
Leprechaun mother ship!
They are secretly trying to fly through the skies disguised as clouds that look like top-hats which is exactly as your photo shows. They are trying
to make people think that they are cloud-ships but they are actually flying top-hats made of fluffy clouds!
These Leprechauns are going to come back in the end-times via these white cloud top-hats. Every eye will see them coming through the clouds in the
last days and all will bow to the
Leprechaun and their top-hat cloud craft. Anyone who refuses to accept the
Leprechaun as their 'messiah' and 'Savior' will go to a very bad place for all eternity where evil dark cloud top-hat
craft will fly night and day forever!!
*SIGH*
