Is it normal to have dreams of the future

I dreamt of being in the high school I'm in now about 5 years before I was enrolled. It's a strange thing indeed. I had read somewhere that this is your brain's fault and you never actually dreamt of the future. Your brain just farted and forgot that it just analyzed what you've seen and experienced and goes over it twice thus making you feel like you've experienced the moment twice. Not sure if this is any true since I read it on a random medical page on the internet. I turned it into a fun game, thought, whenever I feel like I've dreamt of something that is happening right now I keep trying to ruin it so it isn't the way I dreamt it and I feel like I've altered the future lol
