UFOs Behind the Clouds? Why?

In the Philippines, I’ve been observing these strange clouds everywhere especially during daytime. One day I saw a shiny silver disk-shaped object in the Eastern horizon flying westward and it suddenly disappeared behind the clouds.

Almost a year ago I saw an amazing strange cloud just above a local Carnival Park in CCP Complex, Pasay. I know and I could feel there’s something behind that enormous cloud looks like a mother ship.
