I don't dream very often and when I do dream, it is usually about something that is troubling me, or something I am having problems accepting.  I lost my brother in an accident and after that I would dream about him, as if he were still alive, and part of my life.  Then I would wake up and he would not be there.   After that I did not dream very often at all.  I can't say that I don't dream in color, but also, if I do dream, I can't say that I recognize an absence of color either.  Now if I am stressed about work or some big decision, I do dream, but the dreams are never about finding solutions, mostly, they are about avoiding whatever the issue is, and that is immature.  If I ever do decide that I am finally mature and responsible, then perhaps I will dream not only in color but in high definition, as well.
