Dreams!
Have been writing many things off my dreams for 30 years. I use poetry for all my visions, and the main difference is that visions are harder to describe in detail, and for me, tend to be more about my mental observation states than anything else. Visions are kind of "seeing it now", whereas Dreams, for me, tend to be more evaluation and oversight of my daily life.
I am writing a bunch of my dreams on my website in regards to a lot of moments in rock music. However, some of the contents will tend to distort and hurt the idealism surrounding "hit" and "fame" in some of these people.
I have one suggestion!
Get a pencil, paper and put it on the little table next to the bed. When you wake up, write it. You have to promise yourself you won't read any of these until 30 days are gone. (Date the top of the page!)
The not reading is important, to help lessen the "emotional" attachment to what you see, so you can better learn how to interpret what you saw. Only on the 31st day, so to speak, can you look back at that one day and tomorrow the next day.
This is only an experiment, not a fact, in my case, because I have written from my dreams over and over again, to the point where I can re-start them if I want to and need to see where else it will go. It does not always make itself "clear" but at least I was able to re-start it.
Eventually, you learn that the "story" itself is not important, but that the way you "see" things is way more valuable a teacher, and allows you to go way much further in, if you so feel the need, and are willing to undertake the work to do so.
For me, the best book that ever clarified the dream world for me, I had already been tied to my dreams for 10 years then, was the book "The Art of Dreaming". Despite its difficult analogies and sometimes over bearing sense of "this is", when you put that aside, no one, EVER, has put together such a nice road map, for what you can and can not do. There is a part that is difficult for all of us, that he calls "unknown" and "unknowable", and I tend to think that was his way of saying that this separates the student from the master, but I will accept it.
Similarly, things like "The Bardo" (Tibet) uses the analogies of dragons, because in our inner visions we do not recognize the places and it makes us afraid. Dealing with that fear of the unknown, ends up being the biggest teach of all out there and the single biggest symbol and lesson there is to the inner core of our own soul.
There are other fine books out there, and Robert Monroe's 1st and 2nd are very good and can be scary at the same time, but they "blur" the line between dreams and out of the body experiences, which for me are the same thing, not two separate disciplines.
At this point, it is NEVER about what it means, as it is about how much do you really want to learn and understand! The rest is easy and fun! And you can be a kid in the playground all you want to ... how much do you want to?
