have you considered writing down your dreams/nightmares? it can make for a nice book and would allow for an insight into the inner you, or at the very least train your mind; why not post about your recent dreams in this thread?
I had a funny dream yesterday, sparing you the details I dreamt I was a murderer but all my actions were unbeknownst to myself, I hadn't any memories of my deeds until I found a battered piece of wood lodged in a drawer of mine, then I woke up
I hope to resume this dream to rummage some more answers, goodnight
