Harry's Dreams - This Is This Is Going

Harry's dreams in general that we get to see at least are not good. This made me think about Was this meant to be like throwing us off course was it just some weird dream? Like why does the author write this? For this moment is it supposed to lead us astray to think something else is going to happen? Is it just showing you know the trauma from what happened a few chapters before? If I had if this was as far as I had read and I had not read this book many times Then I might have thought that it could be hinting at something because I mean Nagini They just had an encounter with her the Christmas roses they just laid flowers on Harry's parents
