I'm curious to know if frequency of dreaming correlates to anything. Most people I talk to "rarely have dreams" (probably meaning they just dont remember them). For some reason in my case I have a vivid dream every night, sometimes multiple per night, and can't remember the last time my sleep was dreamless. I've heard keeping a dream journal can help you remember/have more vivid dreams, but I only write my dreams dow…
Some people have mostly bad dreams. If I become aware that I am dreaming I stop everything in the dream and "go back to sleep" in the dream. It results in better rest. Everything I've learned in a dream would only be helpful in a world where we wear watermelons for shoes and the trunk of our cars open into hidden ballrooms. It is a really dumb place to spend too much time
Why it is important is because it tells a story about what's going on in your emotional state that you're otherwise unaware of or repressing in conscious experience. It can also provide solutions. It can be a powerful tool for maintaining mental health and wellbeing.
This isn't to say you should be reading "dream interpretation" guides or speaking to interpreters. The point is we already speak the languages of our own dreams because it's our own mind. What seems like nonsense on the surface quickly reveals itself to have a surprisingly clear meaning on introspection from a slightly different angle. Follow your intuition, listen to your psyche, you wont regret it.
