Dreams are, among other things, your brain going over thoughts and feelings that seem incomplete or unfinished. There's definitely meaning in there, but usually you can't really turn that meaning into definitive statements. One thing I've gotten out of reflecting on my dreams is realizing that a certain thing was really stressing me out. When I was awake I was suppressing my reaction to it to get through the day. It wasn't until I saw something analogous show up in multiple dreams and completely change the vibe that I realized how much it was actually bothering me.

I think websites claiming to interpret the meaning of your dreams are bullshit, not because the concept is bullshit, but because the meaning is so tied up in your personal experiences and ways of thinking that you can't make a general form that's going to work for everyone. There might be some broad similarities in how people dream that a could be a useful starting point, but I think to get to the real meaning, the work has to be done in your own brain.
