Do you be alive dreams have a meaning

Mari
Alright I know this isn't too conteroversal but I know people who belive dreams have a significant meaning and there are those who don't. I always rember my dream if it's a lucid dream. I vividly rember lots of deatail. Lots of my dreams have to do with bears chasing me or my boyfriend cheating. Yet the ones that take place with people I know and in places I've been or will be, I always have a dejavu..??? ( not sure how to spell it) but either way once I had a dream of sitting in Lunch having a conversation then a girl with white converse was walking with a guy and it was exactly my dream. I've had things like this happen multiple times and every time I try to change something my mind goes blank and I get a bad headache. So I know this is like hella weird but I wanna see your guys opinions if dreams are significant or not.
