I also do dreamwork and keep a journal, the dreamwork I do is with my spirit guides. I stretch out in bed and meditate a while, then surround myself with white light and call my guides to me (they're usually right there, so they haven't far to travel). I tell my guides what I want/need to know and ask that they tell me or show me in a way/form I will understand and to ensure that when I wake I will remember the dream. When I first began doing this, I began communicating with my guides. I didn't and don't ask life shattering revelations, just run of the mill things: will this check come, when will the check come, is my sister ok....? Things like that. In keeping a journal making note of any/all colors and scents are important.
I still do not have the communication that I'd like to have with my guides, but I can communicate with them. They are here to help, not to make life a bowl of cherries, though. Don't push, don't second guess, simply follow your instincts and listen when you 'feel' or 'hear' something. Toss aside those days when you'd tell Mommy or Daddy about what you saw, heard or felt and their "it was your imagination" reply. Allow yourself to walk in those little girl/boy shoes again, get in touch with the kid inside that's never left. You will find that your "imagination" never left you, you just stopped looking, listening and hearing. *smile*
