Do dreams have a meaning?

Maybe some do. I think most dreams are just bizarre flights of fancy though. I mean my last dream was of me as a police detective and my partner and I were desperately searching for a sock with a bullet hole at this guy's apartment to prove he had used it to subdue the gunpowder residue when he killed the victim so that he would test negative for GSR if he was arrested. We knew it was him, but if we didn't find that sock the whole case against him fell apart.

If there's meaning in that I dream I fail to see it. 🤷‍♂️
