Dream of

In this dream I was in my house and I heard like a Ship's horn was blowing. I walk about 100 ft to the back of my yard and was surprised to not only find a large "ark" there but a multitude of people. The door of the "ark" was open and there were people from every nation on earth gathered in clumps all over . They were dressed in their everyday wear based on where they were from. But as I listened to their conversations, the conversations turned from their native languages to English.
