Strange UFO clouds captured over Washington State, British Columbia, Bulgaria and Mexico

Strange cloud formations have left residents in Washington State and British Columbia perplexed, after showing up in the sky several times this month.

On March 1, 2015 another odd cloud was spotted over Bulgaria. This cloud is almost identically with a cloud captured in Mexico, last year. Both cloud formations are looking out of place in a surrounding clear sky.

It is said that these hole punch clouds actually be evidence of UFO activity while UFOs also have the ability to generate clouds to hide within, like the strange clouds over Bulgaria and Mexico.

Below, short videos of these odd cloud formations.
