Have you ever felt de javu based on your dream?

Once when I was about 12 I kind of dreamed about my 16-year old self, I had a different hairstyle. And when I was 16, after I was at the hairdressers', I realised that I received the same exact cut. It really wasn't in my mind to copy the look I had in that dream, I just had some ideas... and it turned out in that exact way...

yes there are some instances that it felt like deja vu. whenever i encounter this i try hard to remember if that was really a dream i dreamt and i try hard to remember if the actual scene is really the same with my dream. its so frustrating sometimes because i cant remember most of the time. but it feels weird though.

I've felt deja vu before. It's the weirdest feeling. One of the theories on deja vu is that while we sleep our brain is going through life-simulations and occasionally it hits a few notes right so that we feel like we've experienced it before, even though it only happened in a dream.
