Name of song that goes woo and has dream in it?

So at dance cl every week we listen to this song that I really like I just don't know what it is called. It is sung by a girl except 4 chorus where it's is mixed and it goes woo hoo hoo woo hoo hoo hoo hoo hoo during chorus. I can't really understand the girl singing and the onu word I can oil up is dream. The beat changes throughout and at the end there is a whooo like a siren sort of. Any ideas what this song might be?
